Yes and no. Grass or marijuana is generally stronger thanks to sophisticated plant breeding and cultivation methods. However, hash - which usually only contains about 4 -5 % THC - remains weak and unchanged.

Yes and no. This has been a persistent myth for over 40 years but it actually does have some basis in medicine. Basically the psychoactive ingredient in cannabis, THC reduces lutenising hormone (LH) in the genitals. LH triggers ovulation in women and is involved in sperm production in men. Result: a short-term (four to five hour) decrease in reproductive ability. Long term cannabis users, however, build tolerance to this effect and are immune. (1)

If cannabis was legal, the warning label would probably read: "Do not operate a vehicle or heavy machinery". Being stoned leads to a slight impairment of psychomotor and cognitive function. However, in studies, stoned drivers appeared to compensate for their impairment by taking fewer risks and driving more slowly, whereas alcohol tended to encourage risk taking and aggressive driving.

There is a lot of misinformation presented about cannabis and schizophrenia. There is general agreement that heavy cannabis use can precipate schizophrenic episodes but there is no evidence that it can cause the underlying psychotic disorder. Heavy cannabis users can exhibit long-lasting toxic psychosis involving delusions and hallucinations that can be - dangerously - diagnosed as a schizophrenic illness. (4)

No. Like tobacco smoke, cannabis smoke is highly likely to be harmful to fetal development and should be avoided by pregnant women and those who might become pregnant in the near future. quot;Marijuana has no reliable impact on birth size, length of gestation, neurological development, or the occurrence of physical abnormalities.

I only smoke a few draws of cannabis, maybe a whole joint but that 's it. Will this still be detectable on a drug test

I am off to Amsterdam today with my fiancée who doesn't smoke cannabis. My idea is to introduce him to hash cakes but he is allergic to aspirin and I am worried that he might have a reaction to cannabis. Is it possible to be allergic to cannabis? Recently I have had nasal problems when cannabis smoke is around me, my nose gets plugged and sometimes I get a runny nose and occasionally I sneeze to.

The active ingredient THC is detectable in the urine after 48-72 hours in a one-off or occasional user or up to 6 weeks in a heavy user. I only smoke a few draws of cannabis, maybe a whole joint but that 's it. Will this still be detectable on a drug test Yes. Blood and Urine tests involve detecting microscopic amounts of THC (the main psychoactive compound in cannabis) and THC breakdown products so even a few draws or just a whole joint of cannabis would still be detectable. See here for...

The main psychoactive ingredient in cannabis, THC (tetrahydro-cannabinol), is fat-soluble and does enter breast milk and the baby - often, due to the size of the infant, in higher blood concentrations than the mother. However, there is no firm evidence that cannabis or THC can stunt, impair or damage a baby or their growth.

People who have lots of colds, get the flu every year or suffer from a suppressed immune system for other reasons often ask, "How do I improve immune system function?"

NO DEFINITELY NOT, a lot of people worry that their glasses are getting thicker, their prescription is getting stronger and therefore their vision is getting weaker, and they are eventually going to go blind. You may well need different glasses in the future but this is only to get the image in focus and is like getting a bigger pair of shoes. You don't expect to go lame with big feet and you won't go blind with thicker spectacles.

Purity varies, fluctuating on a local basis depending on availability (dealers reduce purity when they don't have as much) but generally, yes, heroin is purer now than it has ever been. Part of this is because former cocaine cartels are now branching out into heroin as well, flooding the market. Higher purity also makes snorting and inhaling an alternative to injecting without too much compromising of the intensity of the high.

Difficult to say. Growing conditions, age, and species can all affect the amounts of psilocybin and psilocin in mushrooms. Psilocin breaks down easily and doesn't survive the drying process. Psilocybin is much hardier (it survived over 115 years in one tested sample). Psycho activity depends on the ratios of the two in the mushrooms, which varies from species to species.

No. This is why so many bodybuilders, appropriately, train to get stronger. If you get stronger, you will get larger. This doesn't automatically mean, that when comparing to different individuals, the larger person is stronger. It simply means that if you take your existing muscle mass and then increase it, it will necessarily be stronger.

Cannabis is the most durable of the hemp plants, and it produces the toughest cloth, called 'canvass.' (Canvass was widely used as sails in the early shipping industry, as it was the only cloth which would not rot on contact with sea spray.) The cannabis plant also produces three other very important products which the other hemp plants do not (in usable form, that is): seed, pulp, and medicine. The pulp is used as fuel, and to make paper. The seed is suitable for both human and animal foods.
