Very simply, drugs make you feel awesome.  That&#x27;s about all there is to it.<p>The problem comes in when you want to maintain the level of awesome ... and can&#x27;t.  That&#x27;s when the detrimental side effects hit.<p>You can be quite a high functioning, normal member of society with a drug habit.  As long as you can pay for it, and as long as it doesn&#x27;t interfere in the aspects of your life you don&#x27;t want it to, one can make a rational case for continuing drug use.<p>Think about coffee.  It&#x27;s great.  It makes you feel great.  It&#x27;s socially acceptable.  It&#x27;s also highly addictive, and the withdrawal symptoms can be nightmarish for some people.  But it&#x27;s not viewed as a bad drug.
