Weed is not addictive. I'll grant most of your other points about it being difficult to think for some people like me and you. However I have known and know many who are as productive, if not more, because of or despite their substance of choice.

For me, I really don't give a damn what kinds of drugs people take beyond heroin, crack, meth, and others that have a clear history of detrimental effects on the individual. As long as you are rock solid and reliable, that's all that matters.

It IS addictive. It can't cause withdrawal symptoms, but absolutely is addictive, like gambling or sex or any other activity that triggers your reward system. I know I felt addicted to pot, failed to quit smoking many times after making the decision to, and kept smoking daily for a year after I had stopped enjoying it. If not addiction, what would you call that?

If you can be sure that someone is reliable, then you are right, there is no reason to have a problem with their drug use. When you are hiring someone or making the decision to invest money with them, you rarely know enough to be sure. Using drugs is a HUGE red flag there, and should say think twice before hiring this person / giving them money.
