&gt;  If we want to solve this problem, we need to provide shelter along with drug rehab services &amp; require weekly clean drug tests as a requirement to keep the shelter.<p>Yes and no.  The question is, are people becoming homeless because they&#x27;re drug addicts or becoming drug addicts because they are homeless?<p>If it&#x27;s the former then yes, clean drug tests - as a requirement to compel them to get better - might help.  If it&#x27;s the latter however, you&#x27;re just going to drive away the very people that you are trying to help.<p>I venture to say that most drug addicts don&#x27;t actually want to be that way.  So throwing them a lifeline and then taking it away because they&#x27;re addicted?  Seems callous and unhelpful.  You&#x27;ll never solve the problem that way.
