    We decided to take buy Mary Joy Pink because the local head shop was out of K2. We should have researched the drug first; we thought it would be just like any of the other synthetic cannabinoids. Big Mistake. All four of us tried the substance.

    Well, the Fuehrer has spoken. Despite providing a regulated, trustworthy alternative to the increasingly poor Cannabis in the UK, Gordon Brown's Labour Government has decided to ban Cannabinoids, alongside less devastating news that BZP (now all but superceded by the safer MBZP) is also to go.

    Coming Out of the Haze neutral exp #95740

    I write this report partially to avoid focusing on a paper due in the next few hours, but mostly because I feel there is a lack of reports by experienced users of so-called 'spice'. As someone who has smoked spice every day for over a year, I feel at least somewhat qualified to speak intelligently on it.

    Pins and Needles on My Face neutral exp #86786

    When I was put on probation for smoking marijuana, I was subject to random drug tests. Not wanting to give up my exploration in psychoactive drugs. My interest for legal alternatives to marijuana was sparked, during my time as a smoker I met many sports player who were commonly tested for drugs.

    Playing With Fire cautionary exp #90178

    I am submitting this report to try and warn people, and get the truth about spice out, this truth being, whether you've ever had a bad experience with it or not, spice is extremely dangerous. I myself have had four bad experiences, that I know for sure we're directly related to my use of spice.

    Serious Addiction cautionary exp #102647

    The first time I smoked spice, was in 8th grade and it did nothing to me, so I kept hitting it. Still nothing. Now in 10th grade I started smoking it again because, everyone I knew was on probation and it was what was available. I hated the taste and the smell. So nasty.

    Almost Accidentally Died New Spice Analogue 5f Mdmb neutral

    I wrote this for Erowid too so its long. I'd call this analogue Synthetic DMT Weed. After receiving a package in the mail from a Chinese vendor, we (my SO and I) soon could tell that this substance was not the 2FDCK we ordered. It was tan colored and of an earthy ground up consistency.

    I don't know why I have not posted about this before, maybe because it was a very scary experience. I will try my best to explain this with great detail to create a picture for you all to see..since that is the best way to describe drug trips IMO. I will also try to not get too personal with it.

    My husband, who has reported here as well, has been enjoying his recent experiments with sex and this legal drug. So much that he's wanted me to share the experience. He' been very careful to give me tiny amounts to make sure I don't overdo it, but I've never even felt any effects from those tries.

It was tan colored and of an earthy ground up consistency. Vendor must have sent us the wrong thing. However, I wanted to make sure it wasn’t still 2FDCK.
