They are freely available to buy and use as they are not covered by the Misuse of Drugs Act 1971. Mephedrone (4-methylmethcathinone) was sold as a \u2018legal high\u2019 until 17 April 2010 when it was made a class B drug under the Misuse of Drugs Act 1971. Numerous deaths and self-harm has been associated with mephedrone use. Effects of mephedrone are reported to be empathogenic similar to 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) and stimulant properties similar to cocaine. Not much is known of the effects of mephedrone on mental health. We present a case of dependence and psychosis in a patient using mephedrone (4-methylmethcathinone). The patient needed inpatient hospital care, was treated with antipsychotic olanzapine and recovered well.<\/jats:p>","DOI":"10.1136\/bcr.02.2010.2780","type":"journal-article","created":{"date-parts":[[2010,11,3]],"date-time":"2010-11-03T13:28:52Z","timestamp":1288790932000},"page":"bcr0220102780","source":"Crossref","is-referenced-by-count":34,"title":["Dependence and psychosis with 4-methylmethcathinone (mephedrone) use"],"prefix":"10.1136","volume":"2010","author":[{"given":"N","family":"Bajaj","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D","family":"Mullen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Wylie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2010,11,3]]},"reference":[{"key":"2025082805220972000_2010.nov03_1.bcr0220102780.1","unstructured":"Home Office circular 010\/2010 \u00e2\u0080\u0093 A change to the Misuse of Drugs Act 1971: control of mephedrone and other cathinone derivatives."},{"key":"2025082805220972000_2010.nov03_1.bcr0220102780.2","unstructured":"Gammell C .
