1-6 weeks, the more frequent of use the longer it is, capping at ~6 weeks

Probably a week or 2. THC can stay in your body for up to 28 days if you use it almost daily.
THC stays in your spit for 24h. Or max. 3 days.
It is very unlikely casual exposure to cannabis smoke will cause THC to be transferred to the blood.
THC is supposed to stay in your system for 30 days. Give or take a few based on your metabolism. But I have heard people say that it can stay in your hair for years. I guess it depends on how long you have smoked and how often.
2 to 5 days
