ABSTRACT
This chapter provides an overview of the use of cannabis in Spain and its regulation, both criminal and administrative, including the effects this regulation has on people who use or are somehow related to the substance. The first signs of cannabis use in the Iberian Peninsula date back to the Neolithic period, according to archaeological and paleontological studies cited by Juan Carlos Us. Since cannabis and its derivatives are included in the Schedules of Narcotic Drugs under International Control, they are regulated both in Spanish criminal and administrative law. In the administrative field, several laws relating to cannabis, and to people using or researching on these substances, coexist under Spanish law. The effects of the prohibitionist policy on people using cannabis are numerous. These effects include the added risk to health, the possibility of stigmatization and, above all, the legal uncertainty. Cannabis Social Clubs (CSC) are a proposal of self-production and self-distribution of cannabis for the personal use of adults.
