Yes. Cannabis use can harm your health. Risks increase with high THC potency, frequent use, and starting at a young age.
Mental health
Cannabis can cause anxiety, paranoia, and panic attacks. Daily use links to depression and social anxiety. In people with a family history of psychosis, high-THC cannabis can trigger schizophrenia. A 2019 study found that daily cannabis use raised psychosis risk by 3 times.
Brain and memory
THC disrupts short-term memory, attention, and learning. These effects last hours after use. Long-term heavy use in teens may lower IQ by up to 8 points. The brain keeps developing until age 25.

Is Marijuana Bad for Your Body
Heart
Cannabis raises heart rate and blood pressure. It can trigger heart attacks in people with heart disease. A 2021 study found that weekly cannabis use raised heart attack risk by 1.5 times in adults under 45.
Dependence
About 3 in 10 people who use cannabis develop cannabis use disorder. Symptoms include craving, withdrawal, and using more than planned. Withdrawal can cause irritability, insomnia, and loss of appetite.
Pregnancy
Cannabis use during pregnancy links to low birth weight and preterm birth. THC passes through the placenta. The American College of Obstetricians and Gynecologists advises against cannabis use during pregnancy.
Driving
Cannabis slows reaction time and impairs judgment. Drivers with THC in their blood have a 2 to 3 times higher crash risk. Mixing cannabis with alcohol multiplies impairment.
CBD products
CBD from hemp contains less than 0.3% THC. CBD may cause liver damage, drowsiness, and diarrhea. The FDA has not approved CBD for most health claims. Buy CBD with a lab test. A lab test shows cannabinoid content and contaminants.
