List of Psychedelic Drugs: Exploring Their Effects, Uses, and Risks

psychedelic drug list

Psychedelic drugs, better known as hallucinogens, have been used for centuries by various cultures for spiritual, religious, and recreational purposes. These substances are known for their profound effects on perception, cognition, and mood, often inducing auditory and visual hallucinations. Recently, there has been a budding interest in the possible therapeutic uses of psychedelic drugs to treat various mental health disorders. This article extensively lists psychedelic drugs, their effects, potential therapeutic uses, and the associated risks.

Psychedelics Classified According to Schedule

The Controlled Substances Act in the United States classifies drugs into five schedules based on their potential for abuse, medical use, and safety. Here is a list of popular hallucinogens organized by their respective schedules:

Schedule I

  • LSD (Lysergic acid diethylamide): A potent synthetic psychedelic known for its powerful hallucinogenic effects and altered perception of reality.
  • Psilocybin: The active compound present in “magic mushrooms,” which induces hallucinations, mystical experiences, and changes in perception.
  • DMT (Dimethyltryptamine): A naturally occurring compound in some plants and animals, known for its intense and short-lived hallucinogenic effects.
  • Mescaline: It is the active compound in the peyote cactus, which produces visual and auditory hallucinations, along with altered perceptions and emotions.
  • MDMA (3,4-Methylenedioxymethamphetamine): Commonly known as a component of the street drug “Ecstasy” or “Molly“, the drug MDMA is a synthetic substance with both stimulant and hallucinogenic effects, often used recreationally for its euphoric and empathogenic properties.

Schedule II

  • PCP (Phencyclidine): Originally developed as an anesthetic, PCP is now a dissociative hallucinogen known for its unpredictable effects and potential for inducing violent behavior.

Schedule III

There are no popular hallucinogens classified as Schedule III substances.

Schedule IV

  • Ketamine: A dissociative anesthetic with hallucinogenic and sedative effects, used medically for pain management and as a recreational drug for its dissociative properties.


  • Salvia divinorum: A plant native to Mexico with dissociative and hallucinogenic effects, used traditionally for spiritual and healing purposes.

Classic Psychedelics

Classic psychedelics are a group of naturally occurring and synthetic substances that primarily interact with serotonin receptors in the brain. For this reason, they are also called serotonergic psychedelics. They are known for inducing profound alterations in perception, behavior, and thought. Here is a list of some of the most well-known classic psychedelics:

Lysergic Acid Diethylamide (LSD)

lsdLSD, or lysergic acid diethylamide, is a synthetic psychedelic drug. Its first synthesis took place in 1938 by Swiss chemist Albert Hofmann. It comes from ergot, a fungus that grows on some grains. LSD is known for its potent effects on sensory perception, mood, and cognition.

  • Effects and duration: The effects of LSD typically last between 8 and 12 hours and can include hallucinations, warped perception of time and space, synesthesia (e.g., “seeing” sounds), and intense emotional experiences.
  • Therapeutic potential: Research has shown promise in using LSD to treat anxiety, depression, and alcohol use disorder. However, we will need more clinical trials to understand its therapeutic potential.
  • Risks: LSD is non-addictive. However, it can cause “bad trips,” characterized by intense anxiety, paranoia, and panic. Additionally, the long-term use of LSD may lead to persistent hallucinations and other perceptual disturbances known as hallucinogen-persisting perception disorder (HPPD).

Psilocybin (Magic Mushrooms)

psilocybin mushroomsPsilocybin is a naturally occurring psychedelic compound found in more than 200 species of mushrooms, commonly referred to as “magic mushrooms.” The use of psilocybin-containing mushrooms dates back to ancient times, with evidence of their use in religious and spiritual rituals in Central and South America.

  • Effects and duration: The effects of psilocybin typically last between 4 and 6 hours and can include vivid visual hallucinations, emotional shifts, and altered perceptions of reality.
  • Therapeutic potential: Psilocybin has shown promise in clinical trials for treating depression, anxiety, and substance use disorders. It can also reduce symptoms of obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD).
  • Risks: While psilocybin is considered relatively safe and non-addictive, it can cause uncomfortable experiences, such as paranoia and confusion. Additionally, there is a risk of ingesting toxic mushrooms when foraging for psilocybin-containing species in the wild.

Mescaline (Peyote and San Pedro Cacti)

MescalineMescaline is a naturally occurring psychedelic alkaloid found in several cactus species, notably the Peyote and San Pedro cacti. Native to Mexico and the southwestern United States, these cacti have been used for centuries by indigenous peoples in spiritual and religious ceremonies.

  • Effects and duration: The effects of mescaline generally last between 8 and 12 hours and can include visual hallucinations, emotional shifts, and heightened sensory experiences.
  • Therapeutic potential: Mescaline has been used traditionally for personal growth, self-exploration, and healing. However, current research on this is limited. As such, it is difficult to determine its potential therapeutic applications in modern medicine.
  • Risks: Mescaline is not addictive, but it can cause nausea, increased heart rate, and high blood pressure. Additionally, some users may experience psychological distress, such as anxiety or paranoia, during the experience.

Dimethyltryptamine (DMT)

Dimethyltryptamine (DMT) is a naturally occurring psychedelic compound in some plants and animals. It has been used traditionally in South America as part of the Ayahuasca brew, a plant-based mixture consumed during spiritual and healing ceremonies.

Reducing the Risks Associated with Using Psychedelic Drugs?

To minimize the risks associated with using psychedelic drugs, consider the following harm-reduction strategies:

  • Research the specific substance and its effects, risks, and proper dosage.
  • Ensure you get the substance from a reliable source to avoid contamination or misidentification. MDMA connects those who need the drug for therapeutic purposes with certified and trusted suppliers.
  • Use the substance in a safe, comfortable, and familiar environment.
  • Have a trusted and sober “trip-sitter” present to provide support and help manage any negative psychedelic effects.
  • Be aware of any personal mental health or medical conditions that psychedelic drugs may exacerbate.

Getting Treatment for Psychedelic Drug Abuse

While most psychedelic drugs may have therapeutic potential for certain mental health conditions, they can also pose risks when used improperly or recreationally. Individuals who struggle with psychedelic drug abuse may benefit from seeking professional help and exploring various treatment options to support their recovery. Here are some steps to consider when seeking treatment for psychedelic drug abuse:

The first step in addressing psychedelic drug abuse is recognizing the signs and symptoms, which may include:

  • Frequent or compulsive use of psychedelic substances
  • Neglecting responsibilities or relationships due to drug use
  • Using psychedelics in dangerous situations, such as driving or operating heavy machinery
  • Developing a tolerance or experiencing withdrawal symptoms
  • Prioritizing drug use over other aspects of life

If you notice any of these signs, a mental health professional, such as a therapist, psychologist, or psychiatrist, can help assess the severity of the individual’s drug abuse and recommend appropriate treatment options. They can also provide support and guidance for addressing any underlying mental health concerns that may contribute to substance abuse.

When it comes to treatment options, there are various options available including:

  • Inpatient treatment: In severe cases or when the individual requires a structured and supportive environment, inpatient treatment centers may help. These facilities provide round-the-clock care and support, including medical supervision, individual and group therapy, and structured daily routines.
  • Outpatient treatment: Outpatient programs allow individuals to attend therapy sessions and other treatment activities while continuing to live at home. This option may suit those with less severe drug abuse cases or who require a more flexible schedule.
  • Counseling and therapy: Psychotherapy, such as cognitive-behavioral therapy (CBT) or dialectical behavior therapy (DBT), can help people develop healthier strategies to cope and address the underlying causes of their drug abuse.
  • Support groups: Peer support groups, such as Narcotics Anonymous, can provide a valuable source of encouragement, shared experiences, and mutual help for individuals in recovery from substance use disorder.
  • Medication: In some cases, other drugs may help manage withdrawal symptoms, cravings, or co-occurring mental health conditions.

Recovery from psychedelic drug abuse often requires ongoing support from friends and family.
