Perhaps, even if we ignore the hundreds of thousands of people who kill themselves withe drugs.
Suicides are usually with prescription drugs, so I assume you're talking about accidental deaths. In that case, far, far more people kill themselves with cars than drugs. Are you against cars too?
We are still talking murder, bribery, extortion, slavery, smuggling just to get those drugs to your street corner.
Or some dude growing it in a back-woods pot farm. Either way it's a silly point because you could argue much the same for alcohol during prohibition. Seems a bit silly to give a life sentence for something most people think shouldn't be illegal.
