Before this question is answered a distinction must be made between ecstasy and ecstasy pills. Ecstasy is one of the many street names for the chemical MDMA (3,4-Methylenedioxymethamphetamine) where as ecstasy pills are tablets which are claimed to contain MDMA but may in fact contain any number of chemicals. MDMA is NOT physically addictive. It is not addictive in the way that drugs such as alcohol, nicotine and heroine are addictive. Having said this, it has been considered to be mentally addictive for some people. Ecstasy pills may contain any number of chemicals that are not MDMA and some of these may be addictive. The two most common addictive drugs that are found in ecstasy tablets are caffeine and amphetamines. Contrary to popular belief, Heroin and other opiates are rarely found in tables sold as ecstasy. In tests preformed by the EcstasyData.org, less then 0.1% of tablets tested contained any opiates. In summary, MDMA (ecstasy) is NOT addictive. Ecstasy pills occasionally contain other drugs that are not MDMA and that may be addictive. The dose and method of consumption (oral) of ecstasy tablets do not often lead to physical addiction to these chemicals.
