    Summary TheDrug.Wiki TripSit

    Khat's potency degrades rapidly after harvesting; fresh leaves (within 24-48 hours) contain the highest cathinone content, while older leaves primarily contain the weaker cathine. Legal status varies dramatically worldwide: it is Schedule I in the United States, Class C in the UK, and illegal in most of Europe and Canada, but remains legal and culturally significant in Yemen, Somalia, Ethiopia, Kenya, and Djibouti. Chronic use is associated with cardiovascular problems, oral health issues, and gastrointestinal complications.

    Within a Yemen Wedding Context neutral exp #44364

    I live in a relatively culturally diverse area of the U.S. Last night I worked valet for a Yemen wedding reception, and after noticing several guests with curiously large, aromatic quids in their mouth I asked an adolescent guest what it was that they were chewing.

    As I haven't read anyone describe this method of khat usage I will now describe an approach different from chewing. I describe here a series of experiences I had more than ten years ago, but I recall them vividly. At the time, I lived in a fairly small town in the Netherlands, with a smallish Somali community.

    End of Week Pick-me-up neutral exp #39714

    I have used various legal and illegal psychoactives before now, however, due to the nature of my work, I felt that I didn't want to risk being prosecuted, and have now decided to use just 'legal highs' - both for recreational purposes, and/or self medication. I live in the UK where Khat is currently unrestricted.

    The Super Kaffe Experience I bought 4 very young plants from a defunct nursery in South Florida. I didn't expect much since the site was run by a nursery that had a long list of neg. feedbacks. WTH, I took the chance. After 6 weeks I got 4 sickly looking plants about 4' long.
