I actually completely agree with you. I just hate it when people are mislead to believe that weed is side-effect free
If someone were to smoke two to three joints a week, there probably wouldn't be any noticeable side-effects unless the smoker has a history of physical or mental health issues.
As of our current understanding, weed is practically harmless as a drug, compared to legal recreational drugs like alcohol and caffine. When it comes down to it, all issues lies within recreational usage and moderation. If a responsible, legal adult wanted to smoke a reasonable amount marijuana in his or her private property, there shouldn't be an issue.
