I have found that Methylone often induces a brief acute bout of acne. The pimples apear about one or two days after a methylone trip. The skin feels greesy. There are usually about 2 to 4 pimples that appear and go away in about 2 or 3 days. This person is in their 30's so acne is not normal in this person. Has anyone else experienced this effect with methylone or MDMA? This effect is one of many reasons I believe that MDMA and it's analouge are unusally poweful drugs that should be used with great moderation.
