With some, they are fine..... others, it has been known to "frazzle" the brain long term, even after giving it up after some 30 odd years or so. If it doesn't hamper mental agility, reasoning and rationale, I am not sure what harm it does but if it clearly adversely damages one's psychological state, its probably best to take responsibility and call it a day before, say, it hinders your ability to work effectively or getting in a car and mowing somebody down.....??
Im with you on most of that Alison but the drink driving thing is much more likely to be drinkers - I just found this;
It is well established that alcohol increases accident risk. Evidence of marijuana’s culpability in on-road driving accidents is much less convincing.
Although cannabis intoxication has been shown to mildly impair psychomotor skills, this impairment does not appear to be severe or long lasting. In driving simulator tests, this impairment is typically manifested by subjects decreasing their driving speed and requiring greater time to respond to emergency situations.
Nevertheless, this impairment does not appear to play a significant role in on-road traffic accidents. A 2002 review of seven separate studies involving 7,934 drivers reported, “Crash culpability studies have failed to demonstrate that drivers with cannabinoids in the blood are significantly more likely than drug-free drivers to be culpable in road crashes.” This result is likely because subject under the influence of marijuana are aware of their impairment and compensate for it accordingly, such as by slowing down and by focusing their attention when they know a response will be required. This reaction is just the opposite of that exhibited by drivers under the influence of alcohol, who tend to drive in a more risky manner proportional to their intoxication.
Today, a large body of research exists exploring the impact of marijuana on psychomotor skills and actual driving performance. This research consists of driving simulator studies, on-road performance studies, crash culpability studies, and summary reviews of the existing evidence. To date, the result of this research is fairly consistent: Marijuana has a measurable yet relatively mild effect on psychomotor skills, yet it does not appear to play a significant role in vehicle crashes, particularly when compared to alcohol. Below is a summary of some of the existing data.
