The increasing potency of hash, with higher levels of THC, raises concerns about its potential consequences, especially among new users and young people whose brains are still developing. The full extent of the consequences of high THC concentrations on the body and brain, particularly the developing brain, is not yet known. Studies have shown that heavy marijuana use is associated with lower life satisfaction, poorer mental and physical health, relationship problems, and academic or career difficulties. It is important to use hash responsibly and be aware of the potential risks.
