yes
Marijuana
no. if you are talking about a clone, yes, but just taking a random stem and throwing it in the group wont do anything.
culture and senstivity
Yes. Depending on what type it is. The stem can strip so it will not close, the washer can break up so it does not seal. A gate valve can corrode and not seal completely. Lots of ways for one to fail.

usually the ingrendients of marijuana that get you high is THC otherwise known as TetraHydraCannibanol and cannabinoids also known as C1,C2 but the part of marijuana you smoke is the flower (Bud) and this is the part of the marijuana that you would get high because it contains the most THC or cannibinoids the stem has ten times less than the flower so most people throw out the stems just like me but you can keep all the stems that you collect and make tea im a stoner to death and i just answered this question
