The first effects of the cannabis tea are usually felt within 30 to 90 minutes, but it can take longer to reach maximum onset. Wait at least two hours before drinking a second cup. Some people do ask does weed tea work and does weed tea get you high? Yes, it works. Although keep in mind that with some of our cannabis teas (Tranquili-tea and Sympa-tea) you may feel no “high” effect at all, or you may just experience a sense of relaxation.
