If you smoke weed (marijuana) on a regular basis you may be concerned about what will happen if you quit. While some experts believe that marijuana can be physically addicting, almost all experts agree that it is psychologically addicting if matched with the right person and used heavily or for long periods of time.

Withdrawal: For some users, the cessation of marijuana use will lead to physical withdrawal symptoms including nausea, sweating and anxiety, according to the Center For Disease Control. These symptoms are reportedly mild when compared to the withdrawal symptoms of other drugs such as heroin or alcohol. In most instances physical withdrawal symptoms will occur if you have been a long-term user or if you are an especially heavy user of the drug. 

Other signs of addiction: If you’re a long-term marijuana user, additional withdrawal symptoms can include severe anxiety, tension, aggression and irritability. There may be a change in your appetite. During your heavy use period you may have lost your motivation to do things. That lack of motivation continues when you first stop using and can last for several months. 

Psychological response: Even if you don't have any physical withdrawal symptoms from stopping marijuana use, it is possible you will suffer from psychological symptoms. Soon after your mind recognizes that your body has stopped ingesting weed it will start sending craving signals throughout your system. A craving is an intense desire to take part in something, such drug use or eating sweets. These cravings can disrupt your concentration and focus on work and school. 

Treatment: Marijuana addiction is typically treated using a multiple-step approach. Behavioral therapy is often combined with medication to alleviate physical withdrawal symptoms while treating the psychological addiction.
