Cannabis laws vary — check local regulations and consult a healthcare provider before use.
By age 30, the brain’s prefrontal cortex is fully developed, making occasional cannabis use less risky than in teenagers.
However, heavy, chronic use may impact attention and working memory.
A 2022 JAMA Psychiatry study noted “small but measurable differences in cognitive scores among daily users.”
Cannabis can relax some users, but high THC doses may trigger anxiety, paranoia, or rapid heartbeat.
The American Psychological Association warns that those with schizophrenia, bipolar disorder, or severe anxiety may worsen with heavy use.
Frequent smoking can irritate lungs; alternatives like edibles or vaporizers reduce irritation but carry other risks.
Moderate, mindful use may offer benefits such as pain relief, stress reduction, and improved sleep.
The National Institute on Drug Abuse notes “about 10% of all cannabis users develop cannabis use disorder.”
Science suggests responsible, moderate cannabis use at 30 is generally safe but should be balanced with lifestyle and health awareness.
