It does harm you awfully, it increases your likelihood of developing contemporary psychosis and schizophrenia (terrible disease whose symptoms include hallucinations and paranoia to name a few), it WILL cause its victim to engage in antisocial activity, it takes away one's ability to learn properly, causes poor short-term memory, disorientation and unpleasant thoughts or feelings of anxiety, depression, and paranoia. These are just the basic negative side effects of cannabis, while there may be popular misinformation about the harm it can do on one's physical health which is verry…  Read more little, there is heaps of evidence on how bad it can be on your mental health and those affects are horrific. Claiming that marijuana has is "not bad at all for you" is a dangerous lie that could cost the mental health or maybe even life of some-one's parent, friend child, grandchild etc. I do agree that there should be more support for the victims of your misinformation, but it can't just be legalized without harsher penalties on the illegal dealers of this innocent medicine that was intended to help people.
