A total of 251 transsexual subjects (163 MtoF and 88 FtoM), attended in the Catalonia Gender Unit, completed self-administrated questionnaires on consumption of alcohol, tobacco, cannabis, cocaine, opioids, and designer drugs. Results were compared with the general population in Catalonia using data from the National Health Service (EDADES 2013 study). Current consumption of alcohol (70.1%), tobacco (46.2%), and cannabis (16.3%) among transsexuals was similar when compared with men (72.1%, 42.1%, 12.8%) and increased when compared with women (57.6%, 35.2%, 5%); the consumption between MtoF and FtoM subgroups was similar.  The use of cocaine was almost ten times more prevalent in the MtoF subgroup than in the FtoM subgroup (1.1%), and in general population (less than 1%).  Only a few reported uses of opioids and designer drugs. In conclusion, the substance use among transsexuals, except for the use of cocaine, was similar between MtoF and FtoM subgroups, and resembled the consumption prevalence among men in the general population. The proportion of cocaine consumers in the MtoF subgroup was up to ten times higher than in other subgroups.
