30. What are soft drugs?
A. Drugs given to babies
B. Chemical drugs which are already found in the body
C. Nutrients which kill the gut harmful microbes
D. Anything that is not nutrients and enters the body through different routes
Ans. B
(Explanation: Soft drugs are natural endogenous substances which are already present in the body. Such as neurotransmitters (dopamine, GABA, epinephrine, norepinephrine), steroids (oxytocin, oestrogen, progesterone), insulin. The body is already programmed to metabolize them and excrete out. Thus these drugs when used are rapidly inactivated.)
