Re: How long does it take for some one to be clean from Heroin?

You ask a couple of questions. I will answer in a purely abstract manner.

The easy one is the science one: how long does it take heroin to clear 
from the body. Heroin is eliminated rapidly from the body, and will be 
clear of the body in a matter of hours (12-24). 
(http://www.moravek.net/ovisnosti/annintmed-01.htm)

However, you then run into some neuropharmacology. In an addict, the brain 
has become accustomed to the presence of heroin, and in its absence, you 
get a whole series of severe effects, known as withdrawal. This can last 
for days.

Then you move into areas which are not well understood. People who are 
addicts may undertake various behaviours, which they may give up when they 
stop addiction. For example, some addicts may steal to finance their 
addiction. Whether they then give up that behaviour (stealing in this 
instance) depends on a number of factors- whether they are supported, have 
a job/ friends, etc. I have no special expertise in this area, and can say 
comparatively little.

Hope this helps
