What This Study Found

The Global Cannabis Cultivation Research Consortium surveyed 6,530 predominantly small-scale cannabis growers from 11 countries about their demographics, methods, motivations, and criminal justice contacts.

The findings were remarkably consistent across countries: most growers came from "normal" rather than "deviant" backgrounds. The clear majority were motivated by reasons other than profit, primarily personal use and self-sufficiency.

Minimal involvement in drug dealing or other criminal activities was reported. Some cross-country differences existed, suggesting that local political, geographical, and cultural factors influence how cultivators operate, but the core profile of the personal-use grower was consistent globally.

Key Numbers

6,530 respondents; 11 countries; majority motivated by personal use; minimal involvement in drug dealing; consistent demographic profiles across countries

How They Did This

Online survey of 6,530 cannabis cultivators from 11 countries conducted by the Global Cannabis Cultivation Research Consortium. Descriptive statistics highlighted similarities and differences across national samples.

Why This Research Matters

Drug policy often treats cannabis cultivation as organized crime. This survey showed that most small-scale growers are ordinary people growing for personal use, with profiles very different from commercial drug dealers. This distinction is relevant for proportionate enforcement and legalization design.

The Bigger Picture

As countries design cannabis legalization frameworks, understanding who actually grows cannabis is important. Policies that treat all cultivation as serious crime may disproportionately target low-risk individuals while failing to address commercial trafficking.

What This Study Doesn't Tell Us

Online recruitment creates selection bias (more tech-savvy, English-speaking growers over-represented). Self-reported data may understate criminal involvement. Different recruitment strategies across countries complicate cross-national comparisons. Non-probability sample.

Questions This Raises

  • ?How do commercial-scale growers differ from the personal-use growers in this sample?
  • ?Would legalization shift cultivation from personal to commercial growing?
  • ?How should cultivation laws distinguish between personal and commercial operations?

Trust & Context

Key Stat:
Majority grew for personal use, not profit, across all 11 countries
Evidence Grade:
Large international sample providing valuable descriptive data, but online recruitment and self-selection bias limit generalizability.
Study Age:
Published in 2015. Cannabis legalization in several countries has since created legal frameworks for personal and commercial cultivation.
