Richard Beasley: Cannabis and the lung
New Zealand has one of the highest reported rates of cannabis use, with about three-quarters of New Zealanders having tried cannabis by the age of 25, and nearly 10% cannabis-dependent by this age.
The potential adverse effects such as the dependence syndrome, impaired adolescent psychosocial development and mental health, and increased risk of motor vehicle crashes are well recognised.
In contrast the potential for habitual cannabis smoking to cause adverse respiratory effects is less well recognised, in part because there has been less research undertaken in this field. In some respects this is surprising, as the usual way to take cannabis is by smoking, and it is known that cannabis smoke contains many of the same constituents as tobacco smoke, including higher levels of some carcinogens.
The full article Cannabis and the Lung by Professor Richard Beasley, is posted on the NZCPR.com website.
