Combining mushrooms and ecstasy. In the early 2000s it was also known as an mx missile, for mushrooms and ecstasy. Back then ecstasy was ecstasy, which is now referred to as Molly by younger people in the 2010s.
Taking psilocybe mushrooms and MDMA (ecstacy) together. Actually regarded quite highly within the drug subculture. The effects rarely last longer than 8 hours. The effects of the MDMA lend a very upbeat feeling to the user, usually resulting in a positive mushroom trip. Because MDMA is a fairly "reliable" good high, but mushrooms aren't (there can be bad trips), the MDMA high helps to stabablize the mushroom trip.
Taking extasy and mushrooms in a combination with each other. The tripp can last until the person goes to sleep(up to several days). Highly discouraged by most veteran drug users.
