According to the North Dakota Attorney General’s office, state legislation which controlled sale of over-the-counter cold medications like Sudafed reduced the number of local labs significantly from 190 lab incidents in 2005 to 40 in 2006.

In addition to the effects of the drug itself, street heroin may have additives that do not readily dissolve and result in clogging the blood vessels that lead to the lungs, liver, kidneys, or brain. This can cause infection or even death of small patches of cells in vital organs.

Ecstasy can also be dangerous to overall health and, on rare occasions, lethal.

Heroin withdrawal begins as early as a few hours after the drug was last used. The body needs time to recover, and heroin withdrawal symptoms result. Heroin withdrawal can occur whenever any chronic use is discontinued or reduced. Users also experience severe craving for the drug during withdrawal, precipitating continued abuse and/or relapse. Major withdrawal symptoms peak between 48 and 72 hours after the last dose and typically subside after about a week; however, some individuals may show persistent withdrawal symptoms for months. Some people experience heroin withdrawal during hospitalization for health conditions other than their addiction. There are a few people in these circumstances that do not even realize they are experiencing withdrawal and think they just have the flu.
