1. A joint alone will get you high as frick. That's why you share them with 2 or 3 of your buddies. When's the last time you gathered up your friends to split a beer or share a glass of wine?

2. A "joint" isn't a set unit of measurement. It can look like a Virginia slim or Schwarzenegger's thumb and the weed varieties inside are limitless.

3. A joint involves paper of some kind. Cigarette paper, cigar wrapper, or healthier raw alternatives, etc. but smoking the paper obviously isn't good for your lungs. It's adorable that you chose that as your method of standardization despite the fact that most people aren't smoking an entire joint alone in paper, they're taking a hit from a glass bowl. Obviously vaporization or water filtration would not fit your fear mongering agenda.

4. To the "we need a DUI-style test" people, what a bunch of hypocrites. You know what's extremely dangerous? Using your hands to hold a burger or large soda while you drive? Should we make fast food/drive thru's illegal? Of course not, it's a billion+ dollar industry. You know what's dangerous? Taking various types of prescription medicines, that don't have eye or breath tests, and then driving with the medicine's side effects. Should we make prescription medicine illegal? Somehow the sky isn't falling. People are told not to drive under the influence. The car says it. The seller says it. The doctor says it. The package says it. Yet sometimes they do and when they cause an incident, they are punished for it. Odd that those circumstances for such serious drugs don't extend to such a harmless plant.

5. Obviously I haven't sat through the decades of propaganda and brainwashing you have had to endure but surely you can see how ridiculous your fears are. At least be logical and consistent and extend your rationale to other, similar situations and areas.
