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)

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.

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.

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. See similar questions...

A yeast infection is not considered a sexually transmitted infection. It is caused when certain internal or external factors change the normal environment of the vagina and trigger an overgrowth of microscopic fungi called Candida albicans. These are the most likely fungi to cause yeast infections as well as infections in other moist areas of the body, such as the mouth (thrush), skin folds and fingernail beds. See similar questions...

Making a template for arch-top windows is similar to making a template for a Trackstar shade. Follow the instructions in How to Make a Trackstar Template. Make sure you extend the template beyond the curve of the window so we know where the curve ends. Again, use the instructions in How to Make a Trackstar Template as reference.

If radiation therapy is given to the ovaries or testes, it may make you permanently sterile. If radiation therapy is given to an area close to the ovaries or testes, it may make you sterile temporarily.

Radiation therapy to an area of your body that is far away from your ovaries or testes should have no effect on your fertility. See similar questions...

It is chemically very easy to produce, and recipes are readily available on the Internet. Some of the chemicals however are hard to get hold of - in the UK at least. Small scale production still flourishes though. Ecstasy, by contrast, requires professional / degree level chemistry and lots more equipment. See similar questions...
