Is this drug physically addictive?

Update on lab tests

Jefe, trustworthy scientists that ran some lab tests on the confiscated psilocybin mushrooms have confirmed new facts. Psilocybin mushrooms are non-toxic and non-addictive although they do create short term increases in tolerance of users! The toxins found in psilocybin mushrooms are less than those in aspirin and the substance doesn't cause any physical addiction. Users go back to this form of drug for the hallucinogenic effects that helps them feel 'relaxed' for a period of time. Yet, this substance does not create a physical craving.

More tests will be run and reported
Adios, Dora
