Marijuana makes your brain grows

and not addictive

Vitamin C dosn't sit at the bottom of your spine and give you flash backs 20 years later.

Thank you, BH; I'm glad to see there was at least one other person who didn't sit through English class high as a kite, trying to grow new neurons!

Now, had I only stayed awake in typing class!

Also, I don't think Vitamin C contains strychnine

The researchers injected rats with HU210, a synthetic drug that is about one-hundred times as powerful as THC,

Whoa. Doode.

Health aspects of cannabis

A marijuana psychosis, long rumored, has been difficult to prove. No one doubts that marijuana use may aggravate existing psychoses or other severe emotional disorders. Brain damage has not been proved. Physical dependence is rarely encountered in the usual patterns of social use, despite some degree of tolerance that may develop. The endocrine effects of the drug might be expected to delay puberty in prepubertal boys, but actual instances have been rare. As with any material that is smoked, chronic smoking of marijuana will produce bronchitis; emphysema or lung cancer have not yet been documented. Cardiovascular effects of the drug are harmful to those with preexisting heart disease; fortunately the number of users with such conditions is minimal.

Recurrent stroke associated with cannabis use

We describe a patient who suffered three ischaemic strokes immediately after cannabis consumption. Other stroke aetiologies were ruled out, and neuroimaging revealed infarcts in different arterial areas as well as evidence of non-atherosclerotic arterial disease, which suggests an underlying vasculopathy of uncertain (toxic or inflammatory) origin. Cannabis use may be associated with ischaemic stroke in young patients, but its mechanism is unclear.

Triggering Myocardial Infarction by Marijuana

Marijuana use in the age group prone to coronary artery disease is higher than it was in the past. Smoking marijuana is known to have hemodynamic consequences, including a dose-dependent increase in heart rate, supine hypertension, and postural hypotension; however, whether it can trigger the onset of myocardial infarction is unknown.
[...]Smoking marijuana is a rare trigger of acute myocardial infarction. Understanding the mechanism through which marijuana causes infarction may provide insight into the triggering of myocardial infarction by this and other, more common stressors.

Cannabis and the brain

Central effects of cannabinoids include disruption of psychomotor behaviour, short-term memory impairment, intoxication, stimulation of appetite, antinociceptive actions (particularly against pain of neuropathic origin) and anti-emetic effects. Although there are signs of mild cognitive impairment in chronic cannabis users there is little evidence that such impairments are irreversible, or that they are accompanied by drug-induced neuropathology. A proportion of regular users of cannabis develop tolerance and dependence on the drug. Some studies have linked chronic use of cannabis with an increased risk of psychiatric illness, but there is little evidence for any causal link.

Health care use by frequent marijuana smokers who do not smoke tobacco.

Daily marijuana smoking, even in the absence of tobacco, appeared to be associated with an elevated risk of health care use for various health problems.

The relationship between early age of onset of initial substance use and engaging in multiple health risk behaviors among young adolescents.

Even when considering sociodemographic factors, early age of onset of cigarette use was the strongest correlate of the number of health risk behaviors in which these young adolescents had engaged. Early onset of use of other substances was also associated with a clustering of health risk behaviors among this sample of middle school students. The findings suggest that screening for early experimentation with tobacco and other substance use will help identify young adolescents at increased risk for engaging in multiple health risk behaviors.

And remember folks, we don't discuss recreational drug use here, so please don't, if you'd like to continue a sensible conversation on this interesting topic.

Lets see here ,...

Alcohol is a toxic waste product of Yeast.

Nicotine is one of the most poisonous and addictive alkaloids known to man.

THC is harmless and healthy.

Of course weed is illegal this is just a typical example of the Government protecting the People.

Well, as it always happens, the thread is boiling down to a "Weed should be legal" thing.

This is why we frown upon these threads. Whether there is a medicinal or scientific value to marijuana is never long the topic of discussion, it always turns into a, "I should be allowed to be stoned" thread.

That is nothing more than embracing ignorance, and we aren't about that.
