It is very unlikely casual exposure to cannabis smoke will cause THC to be transferred to the blood.
Beer does not clean THC out of blood. THC can stay in the body for weeks depending on the person.

As long as your on it
No, not completely. Delta 9 THC, the active ingredient in cannabis, is taken up by many types of cells, including fat cells (adipose tissue). In heavy users, THC is released from adipose tissue over time, sometimes as long as several weeks (that not even dialysis can completely get rid of).
Depending on how much your intake of THC is. If your intake of THC is a couple times a week it will stay for about 3-4 weeks. If you only smoked once it would stay in your system for 48 hours.
THC stays in your spit for 24h. Or max. 3 days.
About a year maybe longer depending on your shoe size
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.
Thc can be detected in the saliva for 5 to 10 days depending if you are a heavy user.
