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.
