Myth vs. fact

Let's clear the air.

The most repeated cannabis myths, checked against the best available research. Tap any myth to see the facts.

MYTH

“You can fatally overdose on cannabis, like alcohol.”

FACT: Cannabis has the widest safety margin of any drug studied

Its margin of exposure is above 10,000, compared with alcohol's "high risk" rating¹. The National Academies found insufficient evidence of any link between cannabis and overdose death¹¹. Edibles can still be too strong if you take too much too fast, so wait at least 2 hours before having more²⁶.

MYTH

“Cannabis is just as dangerous as alcohol.”

FACT: By every major measure, alcohol is more harmful

Experts ranked alcohol the most harmful drug overall². It causes about 178,000 U.S. deaths a year³ and is linked to at least 7 cancers⁷. Dependence risk is 22.7% for alcohol versus 8.9% for cannabis⁸.

MYTH

“Cannabis has no medical value.”

FACT: The FDA has approved cannabinoid medicines, and HHS recognizes medical use

The National Academies found conclusive or substantial evidence for chronic pain, chemo nausea, and MS spasticity¹¹. The FDA has approved Epidiolex, Marinol, Syndros, and Cesamet²¹, and HHS found a currently accepted medical use⁵⁵.

MYTH

“Marijuana is a gateway drug.”

FACT: Most people who use cannabis never move on to other drugs

That's the National Institute on Drug Abuse's own finding⁷². The 1944 La Guardia Report also found no evidence that cannabis led to other drug use⁵⁸.

MYTH

“Smoking cannabis causes lung cancer, just like tobacco.”

FACT: Large reviews found no link to lung cancer

The National Academies found moderate evidence of no statistical association between smoking cannabis and lung cancer, or head-and-neck cancers¹¹. Prefer to skip smoke altogether? Edibles, tinctures, and vapes are options²⁷.

MYTH

“Legalization makes more teens use cannabis.”

FACT: A study of 1.6 million students found no increase

Using national youth surveys from 1993 to 2019, researchers found little evidence that recreational or medical marijuana laws encourage teen use⁵³.

MYTH

“THCA is a harmless loophole that does nothing.”

FACT: THCA is non-intoxicating raw, and becomes THC when heated

Raw THCA doesn't get you high, and it's being studied for anti-inflammatory and neuroprotective effects^{19 46}. Smoked or baked, it converts to THC¹⁸. That's why lawmakers now count it as "total THC"^{29 36}.

MYTH

“Cannabis makes people violent.”

FACT: That claim came from 1930s propaganda, not science

See The Lies. The 1944 La Guardia Report found no link to violence⁵⁸, and alcohol ranks highest for harm to others².
