I hope you're not referring to marijuana, it can't truthfully be said that it's harmless, not even close. And any drug can be harmful, just look at the side effects of Tylenol.

He's probably referring to marijuana, and there's numerous studies that would both support and contradict that notion.

Anything consumed in excess can be harmful in the short-term and long-term, including food, water, or oxygen.

The thing that is illegal, thc, is hardly dangerous. Inhaling burnt cannabis might be, but then again nobody smokes 24 or 48 blunts a day.

I have smoked and ingested marijuana for over 20 years and my doctor says I am in absolutely wonderful condition for my age.

>marijuana makes you smarter, stronger, and happier

Prove me wrong. And I was high when I wrote this. Zero mistakes, flawless use of internet comment section.

Just because YOU didn't get cancer from smoking cigarettes, doesn't mean that smoking cigarettes doesn't cause cancer.

There are significant health risks associated with smoking pot, including serious mental health issues for some people. Quoting from http://www.drugabuse.gov/publications/drugfacts/marijuana:

Research clearly demonstrates that marijuana has the potential to cause problems in daily life or make a person's existing problems worse. In fact, heavy marijuana users generally report lower life satisfaction, poorer mental and physical health, relationship problems, and less academic and career success compared to their peers who came from similar backgrounds. For example, marijuana use is associated with a higher likelihood of dropping out from school. Several studies also associate workers' marijuana smoking with increased absences, tardiness, accidents, workers' compensation claims, and job turnover.

I know "correlation doesn't equal causation". But there are clear risks associated with marijuana use that should not be dismissed so casually.

> Several studies also associate workers' marijuana smoking with increased absences, tardiness, accidents, workers' compensation claims, and job turnover.

In other words, marijuana users appreciate life more and make for bad slaves.

Btw, smoking is not the only way of consuming marijuana. There are also water pipes and green dragon.

I'm sorry, but I don't buy that being honest (showing up when you said you'd be there, and showing up period, and in general being a trustworthy individual) makes you a slave. I'm sure there's plenty of habitual smokers who are great dependable employees who would be insulted at this idea.

>Btw, smoking is not the only way of consuming marijuana. There are also water pipes and green dragon.

And these differ from smoking how?

Green dragon is a drink.

"Water pipes" or "bongs" still involve smoking, but the smoke is passed through water. I don't know to what extent this reduces the ill-effects of inhaled smoke.

I think you prove my point perfectly. If you hadn't dulled your intellect by smoking so much weed, it might be obvious to you that your current state of health has no bearing on whether smoking marijuana causes lung cancer or other deleterious effects.

You seriously think that byproducts of incomplete combustion are harmless? Even wood smoke is terrible for your health. So is tobacco smoke and marijuana smoke and just about anything else that you can burn.

You commit the same fallacy... his current state of intellect has no bearing on whether smoking marijuana causes a decrease in mental functioning.

Aside from smoking, vaporizing and eating edibles are popular and safe ways to ingest marijuana.
