Tea can also be a component of acne mask and it may serve as a toner or cleanser. Although most herbs can be chopped down into pieces, powdered and steeped into hot water (preparations involving alcohol should be avoided because they may dry up the skin), not all of them qualify as tea.
How long does weed stay in your system (blood)? In the blood weed can be present for up to 2-3 days after use, however in cases of heavy and frequent use it can be detected after up to 2-3 weeks.n the tests THC is immediately detectable as soon as the first inhale of weed, and reaches its peak concentration at around 9 min into smoking. It takes between 3-12 hours for THC to decrease at an undetectable level after the last inhale.
Consider the following example: the half life of the THC in your system is 5 days. After smoking pot, your THC level in urine is about 100 ng/ml, but 5 days later it will be about 50 ng/ml. You will pass a urine test for sure the next day. Every case is different, though, and too many factors influence THC half life, so we can only approximate how long marijuana stays in the human body.
