Hard and soft drugs
Hard drugs are drugs that lead to physical addiction and potentially death. Making, selling, or using drugs other than for approved medical purposes is illegal in most countries. Hard drugs include opioids like heroin, hydrocodone, oxycodone (Oxycontin) and morphine. Benzodiazepines are another class of hard drugs and include diazepam, alprazolam, clonazepam, and lorazepam. Hard stimulant drugs include methamphetamine (meth), cocaine, and nicotine. Drugs such as alcohol and nicotine are legal to sell in many countries and are often taxed.
