- Identify if there are changes in the main substance of psychoactive substance use during the Covid-19 pandemic. - Identify possible divergences in characteristics of the general sample with respect to the sample made up of women.

It will be used data collected in the database of patients in follow-up with the addiction consultation service in two periods of 6 months, one prior to the pandemic situation due to Covid-19 and another corresponding to same period in 2020. A descriptive analysis is carried out by applying chi-square statistic, performing the analysis by subgroups according to gender.

84.8% of total sample are men. Results show that there are no statistically significant differences between periods in main substance of consumption. Despite this, differential trends can be observed in the sample that correspond to women with respect to the global sample and that of men.

Taking into account the low number of women that make up the sample, the fact that differential trends are observed could indicate possible differences, which in case of increasing the sample size could acquire statistical significance and that this it would be specific to women subgroup.

No significant relationships.
