[Addictive inhalants-A challenge for the lungs]

The use of inhaled psychotropic substances is widespread in our society. In addition to the wide variety of tobacco-containing smoking products, e‑cigarettes, cannabis, sniffing substances, cocaine and heroin are consumed by inhalation. While the harmful effects of most tobacco-containing smoking products on the lungs have been sufficiently researched, there is still a lack of scientifically sound evidence for many other substances consumed by inhalation. In particular, for novel products, such as e‑cigarettes and tobacco heaters, there is a lack of independent standardized data demonstrating reduced health risk as a result of lower exposure to harmful substances. Clear conclusions are also currently not possible for the long-term effects of cannabis use on the lungs and respiratory tract. For the inhaled use of cocaine and heroin, on the other hand, considerable damage to the lungs can be documented, especially in the case of extensive and chronic use.
