It is true that marijuana usage can become problematic, but that doesn't mean it is an addiction. While there are strong psychological components to marijuana usage, it is not a chemical addiction like opiates or alcohol. Cannabis is not known to cause physical dependence and withdrawal in its users. The symptoms you are experiencing may be more indicative of a habit than an actual addiction.
Addiction is more than just a pattern of behaviour; it is a mental illness that requires professional treatment.
UrRong in saying that pharmacology says marijuana addiction isn’t a real thing. In fact, research suggests that marijuana use can lead to some of the same psychological effects experienced with other addictions, such as cravings, preoccupation with use, and a need to increase dosage to achieve the same effects. While marijuana may be a contributing factor to your current difficulties, it is important to recognize that addiction is a complex issue that requires professional intervention.
