Cannabis, Health & Risks — An Honest Overview

Cannabis is neither harmless nor demonic. The truth lies in clear risk categories: high for adolescents, pregnant women, and those predisposed to psychosis — moderate for adults with controlled consumption.

TL;DR: Clear risks: consumption before 21 (brain development), pregnancy, family history of psychosis, driving/machinery. Addiction risk ~9% lifetime (alcohol 15%, nicotine 32%). No documented fatal direct overdose. Smoking increases bronchitis risk, vaporising significantly less.

The Risk Map

HIGH: consumption before 18/21, pregnancy/breastfeeding, active psychosis or family history, combination with alcohol, driving/machinery.

MODERATE: daily high-dose consumption in adults, chronic bronchitis (smokers), reduced motivation with continuous use.

LOW with controlled adult consumption: occasional, vaporised, socially appropriate, without alcohol/driving.
