I really don't know why anyone would smoke weed or even sigs inside the shower, where not only is a bit questioning, but also the heat of the water l may affect you.
As to some of the above who make fun of you using Swim-pay no attention-you are new and don't know the ropes-I guess they think by redicule is the way to learn rather then tell you it is not used here since you already have a screen name unlike the places you learned to use that one for all word.
Low blood pressure-sounds like it, but since you were also using the shower (heavens know why??), it may have brought a reaction. If you are using those pills as well as using weed for a while and never got such a reaction, I would say the questionable method of smoking while the hot water running on your neck and shaulders, could have created some reaction.
