Advocates of cannabis use as a recreational drug have long argued that it is safe. However, a new study has shown that smoking weed has a negative effect on brain function.
The main active constituent in canabis is Delta(9)-Tetrahydrocannabinol (THC). The study looked at the effect of increasing the dose of Delta(9)-Tetrahydrocannabinol (THC), combined with tobacco, on users compared with the control group who did not smoke cannabis. Before now no one had studied the effects of increased levels of Delta(9)-Tetrahydrocannabinol (THC) on behaviour.
As the strength of weed increases, and as some states have now legalised recreational cannabis use the study is very timely.
The results showed that users showed worsening motor skills and processing times. The study warned that consequently recreational cannabis use poses a public health and safety issue.
