The author, Gary Potter, explores who is involved in cannabis growing. At a basic level features – demographic and ‘ideological’ – common to most cannabis growers (although varying by national and local social cultural and legal contexts) are considered. At a deeper level a typology of cannabis growers is offered based predominantly on motivation and ideology, and accommodating international variations. Although a large number of cannabis growers seek no financial reward whatsoever for their involvement in what is essentially an act of drug trafficking, others are financially motivated, though both are equally motivated by non-financial ‘drivers’.
