3-methylmethcathinone and Amphetamine-Related-Disorders

3-Methylmethcathinone (3-MMC or metaphedrone) is a synthetic cathinone, recently introduced in the market of the new psychoactive substances (NPS), initially to replace mephedrone (4-methylmethcathinone or 4-MMC), and rapidly widespread among drug users. 3-Methylmethcathinone is legally controlled in many countries, but is still easily available for purchase from websites, and frequently found in recreational settings. Most toxicological data on this drug come from human case reports of intoxications. Thus, further investigation on their pharmacological and toxicological properties is necessary to evaluate its potential harmful effects. The present work provides a review on the available data about 3-MMC legal status, chemistry, patterns of use, prevalence, biological effects, toxicokinetics, toxicity and factors affecting stimulant/toxicological effects.

The study presents the characteristics of the use of new psychoactive substances (NPS), the perceived problems experienced by users, and the reasons for cessation or cutting down. The research focused mainly on synthetic cathinones and the use of 3-MMC in Slovenia.. In order to research the characteristics of NPS use, we used a questionnaire which had been developed to determine the characteristics of the use of ATS and cocaine in the context of nightlife and was elaborated in our study on the use of mephedrone. The final non-representative sample included 249 users of NPS from Slovenia, who had completed an on-line survey over a period of 5 months in 2014. Part of the sampling was conducted on the ground and with the help of peer-groups. DrogArt's outreach workers and correspondents visited open public places, clubs, and discotheques to encourage users to participate in the survey.. Most users of NPS in Slovenia have tried NPS from the groups of synthetic cathinones and amphetamines. Most respondents included in the sample (67.9%) have tried 3-MMC, while 43.0% have tried methylone and 37.3% have tried mephedrone (4-MMC). Users attributed greater risks to the use of new drugs and preferred the effects of traditional drugs to those of new drugs. The most frequently reported problems were depression (55.2% of users), concentration difficulties (44.0%), damage to the mucous membrane of the nose and to the throat (39.8%), feelings of fear and anxiety (39.4%), and tingling in the arms or legs (34.4%). The main reasons for cutting down or discontinuing the use of NPS were 'fear of the health consequences', 'actual health consequences', and 'growing weary of using'. Among users of NPS, 7% have sought help, while 9.1% have considered doing so. The results also highlight differences between the NPS drug markets in Slovenia and the United Kingdom.. In 2014, the most frequently used NPS in Slovenia were synthetic cathinones such as 3-MMC. Users experienced various problems related to the use of NPS. However, they are familiar with recommendations on harm reduction and want additional information on the harmful effects of the use of NPS. Based on the obtained results, we can develop specific interventions in the area of harm reduction.
