Caution

Marijuana (Cannabis)

46/100
RemedyRank score

Not a home remedy: a psychoactive plant with real risks, especially for youth and mental health -- distinct from its non-psychoactive relative, hemp, which can be used healthfully as a food.

🛑 RemedyRank warns against this

A psychoactive drug, not a home remedy. This site does not recommend it for any condition.

This page exists so the reasons are written down plainly, not because the practice is recommended. Nothing is sold here. If a doctor has prescribed something for a diagnosed condition, follow their guidance — that is a decision between you and them, and it is a different thing from trying this at home.

🌱 What it is

Marijuana (cannabis) is a plant containing THC (tetrahydrocannabinol), the compound responsible for its psychoactive "high," along with CBD and other compounds. It is smoked, vaporized, or eaten in food products, in forms whose THC potency has risen sharply over recent decades. Hemp is the same plant species bred to be very low in THC and is not psychoactive -- hemp seed and hemp seed oil are ordinary, healthful foods and are covered separately (see Hemp Seed).

📜 Where it comes from

Cannabis has a long history of both fiber and medicinal use across ancient China, India, and the Middle East, where it appears in early medical and religious texts for pain and various ailments, and its psychoactive use also has ancient roots in parts of Asia and the Middle East. Its recreational and medicinal use spread into Western countries over the 19th and 20th centuries, becoming the subject of significant legal and cultural change in recent decades. It is treated here as a substance with real documented risks rather than a home health remedy.

🥄 How to use it

This site does not recommend marijuana use for any condition. If a physician has prescribed a specific cannabinoid medication for a diagnosed condition, follow their guidance exactly. Otherwise, this is not a home remedy to try on your own.

Why it works: Researchers explain marijuana's psychoactive effects through THC's action on the brain's cannabinoid receptors, while addiction medicine and psychiatric research have documented particular risks for the developing brain and for mental health.

⚠️ Cautions

  • Marijuana is never recommended here as a treatment for any condition. Its risks are real and well documented: regular use, especially starting in the teen years, is linked to a higher risk of anxiety, depression, and psychosis or schizophrenia in those with a personal or family vulnerability; today’s much higher-potency products have sharpened this risk compared to decades past. It impairs memory, attention, coordination, and judgment for hours after use, making driving or operating machinery dangerous. It is addictive for a meaningful share of regular users, especially those who start young, and heavy long-term use has been linked to cannabinoid hyperemesis syndrome (cycles of severe vomiting), lung irritation when smoked, and possible harm to a developing fetus in pregnancy or a nursing infant -- it should always be avoided in pregnancy and breastfeeding. As with any mind-altering substance, this site’s position is that psychoactive drugs used purely to alter mood or perception are not a wellness practice worth pursuing, and are never a substitute for addressing the underlying reason a person feels they need one. If use has become hard to stop, this is treated the same as any other addiction here: a real health concern deserving compassion, honesty, and real support -- from a doctor, counselor, or a program such as SAMHSA’s National Helpline (1-800-662-4357) -- not shame or secrecy.
