Hemp has environmental uses such as in the production of paper, which would decrease the rate that trees are being cut down. Marijuana criminalization has led the government to prohibit its use even for this. Drug legalization would prevent any government excuse to ban the industrial use of hemp. The drug war primarily helps the synthetic-fibre, wood pulp, petrochemical, and pharmochemical industries because they profit from hemp substitutes which are frequently less useful than hemp itself.
