A.M.S. is the abbreviation of Anti Mold Strain and stands for a hybrid bred by mating Swiss Sativa and a Swiss Indica from the Ticino region. A.M.S. is averaging 15% on THC and over 1% on CBD, making it a very interesting strain for many medicinal users. The CBN level is also quite high at an average of 0.7%, so the high is very relaxing and not too trippy.
