Saying that weed has never killed anyone is the same as alcohol has never actually killed anyone. People die from liver failure, stomach cancer and other things associated to drinking. Well actually the same happens with weed. As a gateway drug pot has been found in many OD patients, suicides and even cancer. Pot smoke is actually MORE harmful than tobacco smoke. Fact is there are more chenilles in a joint once it's lit than a cigarette.
Pot also like alcohol also impares your judgement and ability to drive, it is a depressant and slows reaction time.
Alcohol is deemed legal and used by more people than pot. This alone adds to more deaths per capita. While it is true that alcohol is so addictive that it can kill you from stopping the fact is, it is legal. So, if a cop shows up to your house and you have a joint in your tool box, stand by because you deserve what's coming to you. Same as if you are under age and have cigarettes or alcohol.
Do a little more reading on your wonder drug, the effects on the body and how it relates to the subject. Mayoclinc online is a good source of factual medical information and I reference them in this posting.
