Behavior is the prime mover of chemical addiction. In fact the neuro-chemistry is same whether it is behavior or a chemical. In my life I have been addicted to: Working out, stress, sex, work, pot, nicotine, and booze. Thankfully I skipped over coke, anger, meth, and gambling. Making a distinction between alcohol and drugs is silly. Addicts create their own community where their behavior is acceptable.
