There is a big difference between criminalising/punishing people and hyping drugs as all those cannabis activists do. Smoking may be your personal choice - but I honestly think it would be bad for society if the majority did it. There is a reason that under current law using/selling drugs is punished: society as a whole might suffer.
Those "cannabis activists" are most likely a (very vocal) minority... I don't know of anyone that _seriously_ hypes pot as a safe thing, and we have a lot of smokers here in Quebec (last official numbers were ~15% in 2015, pretty sure it's actually higher than that), so it's not hard to find one. There was probably "alcohol activists" back in prohibition, so I'd say this could also be a side-effect of its illegal status.

There was also a law that prohibited alcohol for a time. I am also prohibited under Canadian law from pretending to practice witchcraft. Talking about differences, there is a big difference between legal and legitimate.
"There is a reason that under current law using/selling drugs is punished: society as a whole might suffer."
Hate to break it to you, but the "war on drugs" was and is really a war on minorities, and a war against alternatives to prescription drugs (among about a half dozen other nefarious reasons).
When I was 12 I would have believed that "drugs are bad and what's why they're illegal" - I'm no longer 12.
Also society doesn't has the right to keep some drugs illegal while keeping others legal.
Stop criminalising someone who chose another drug than you prefer.
Illegal should it be when it harms others.
