Quitting smoking weed can cause withdrawal symptoms, which can range from mild to severe discomfort, but are not usually dangerous. Some common withdrawal symptoms include strange dreams, anxiety, restlessness, irritability, anger, sweats, chills, changes in appetite, and nicotine withdrawal (if you smoke cannabis with tobacco) . These symptoms usually peak about four days after you stop or cut down, and they will probably be more intense if you stop completely rather than cutting down, or if you smoke cannabis every day or most days.

Quitting marijuana can deliver substantial benefits, including physical and mental benefits such as improved memory, mental acuity, and attention span. Brain receptors return to normal function, and sometimes users report experiencing withdrawal symptoms, especially insomnia, up to a year after quitting. It is common to experience cravings after quitting, especially when around people, locations, or situations that triggered past marijuana use. It is important to develop a social network with other people who do not use marijuana to help cope with cravings and to build a support system.

It is worth noting that marijuana withdrawal symptoms are not physically dangerous like some other drugs. However, someone who has long been accustomed to using weed to mitigate their depression or anxiety might not have the tools to cope with these feelings while sober, and the rebound of anxiety or depression after quitting weed can potentially lead to relapse. In general, weed withdrawal symptoms develop within 24-72 hours after someone decides to quit weed cold turkey, and those symptoms grow in severity during the first 7 days, at which point they peak in intensity.
