Cannabis may be addictive. Although there is evidence that cannabis does help fight certain addictions, there are also studies that show frequent use, especially for those who begin at a young age, are at increased risk of developing a problem with marijuana dependency down the road.
Cannabis may be a gateway drug. Even though numerous studies show contrary evidence, there are many people — including some addiction experts — that feel cannabis use leads to the use of harder drugs. One argument along these lines is that cannabis itself is getting much stronger. For example, cannabis in the 60’s and 70’s typically had a THC level of about 1%. Today’s THC levels can exceed 30%. Cannabis may increase anxiety. While studies show that marijuana may alleviate symptoms of anxiety, there are contradictory studies that reveal regular users may actually be at increased risk of anxiety, including social anxiety.
