1. You can buy shopping carts full of alcohol at one time if you want. I've watched people purchase thousands of cigarettes in one purchase. Having essentially unlimited access to addictive drugs wouldn't be out of the social norm.
2. I think some drugs would become cheaper, and other drugs would become more expensive. Drugs with limited supply would become cheaper as more production/supply chains open up. Think cocaine, heroin, and some pharmaceuticals without large overseas labs. There are inefficiencies in the illegal drug trade that legal trade could smooth over as well: better payment methods, more open price negotiations, legal settlement for disputes, reduced employee churn from violence/arrest, reduced bribes/corruption related charges.
3. Regardless of the price of drugs, the overall price would be smaller, as illegal drug use has huge externalized costs. Everything from corrupt governments to increased health care utilization to wasted law enforcement resources to destroyed human capital.
4. The existence of an available quality tested market would force the black market to compete more on quality.
