Wof is true regarding tolerance occurring in regular opium abusers
Correct Answer: No tolerance occurs to constipating and miotic actions of morphine

It is paly pharmacokinetic (enhanced rate of metabolism), but mainly pharmacodynamic (cellular tolerance). Tolerance is exhibited to most actions, but not to constipating and miotic actions. Addicts tolerate morphine in grams: lethal dose is markedly increased. Ref:- kd tripathi; pg num:-473
