First of all…if you notice your family member drastically changing and you’re concerned with some kind of drug/alcohol abuse call a treatment center like Turning Point Centers immediately and start doing your homework.
Research has shown that the purity of heroin lessens the further away from the Mexican border. The reason why is because it’s expensive to ship heroin and longer the distance the more costs. When this happens the dealers have to “cut” the heroin to make more profit. They do this by adding solutions/substances to make their heroin last longer. This is only true for about the first 900 miles or so from the border and then as research approaches the northeast the purity goes up again. The reason for this is because heroin is now coming in from the southeast corners of Canada. The danger in living in a region (besides the obvious) is the more pure the heroin the more dangers/risks involved for the user.
Watch for the signs/symptoms of heroin use and call a treatment center immediately for help!
