Does smoking marijuana cause men to become impotent?

Question

A great reason to not smoke!!! Can you become more errect if you discontinue using marijuana?

Answer 1

smoking ANYTHING will effect a man's blood circulation, which will ultimately affect his erections. Smoking restricts the oxygen content of the blood vessels, thereby reducing the flow to the penis. its a GREAT reason to stop smoking, but not JUST pot.

Answer 2

No, smoking marijuana does not cause a man to become impotent. In fact, many people find that marijuana smoking increases sexual desire.

Answer 3

No thats just a myth. I have plenty of male friends who used marijuana on a daily basis and have had one or more children. Pot does nothing to that area of a mans body.

Answer 4

Smoking causes narrowing of arteries and veins. A penis needs to get good blood flow to get hard, so yeah. Quit smoking and get harder.

Answer 5

Ummmm.... I don't know. But smoking does give them the munchies, makes them eat more. The more they eat the bigger their belly gets and that makes their penis look smaller. LOL

Answer 6

this is not true any one who smokes can tell u when u smoke u can focus 100 percent better than ever before and there for can become harder than ever before

Answer 7

4 kids...5 years...
Nope. No problems

Answer 8

Of the approximately 400 different chemicals found in Cannabis, the main active ingredient is tetrahydrocannabinol (delta-9-tetrahydrocannabinol, THC). THC can degrade to other cannabinoids, such as cannabidiol or cannabinol, which can make one feel sleepy and disoriented. Different cannabis products have different ratios of these and other cannabinoids. Depending on the ratio, the quality and nature of the "high" will vary.

THC has an effect on the modulation of the immune system, which may have an effect on malignant cells, but there is insufficient scientific study to determine whether this might promote or limit cancer. Cannabinoid receptors are also present in the human reproductive system, but there is insufficient scientific study to conclusively determine the effects of cannabis on reproduction. Mild allergies to cannabis may be possible in some members of the population.

A study has shown that holding cannabis smoke in one's lungs for longer periods of time does not conclusively increase THC's effects.[28]

List of effects
Cannabis has a broad spectrum of possible cognitive, behavioral, and physiological effects, the occurrence of which vary from user to user. Some of these are the intended effect desired by users, some may be considered desirable depending on the situation, and others are generally considered undesirable. Users of cannabis report that these kinds of effects are more often produced by the sativa species of Cannabis.

Cannabis also has effects that are predominantly physical or sensory, widely believed to be more common with the indica species.

Cognitive effects
Short or long-term psychosis/schizophrenic disorders in some young users [29] Varying amounts of paranoia and anxiety in some users[30] Loss of coordination and distorted sense of time in some users[31] Impairment of short-term memory in some users[32] Auditory or visual hallucinations at high doses in some users[33] Increased mental activity, like metacognition and introspective or meditative states of mind in some users[citation needed] Relaxation or stress reduction in some users[citation needed] Mild entheogenesis (e.g. per Rastafarian users, more "Jah-Vibrations") in some users Behavioral effects
Varying degrees of euphoria and feelings of well-being Physiological effects
Antiemetic properties (in moderate doses) [34] Lowered intraocular pressure, beneficial to glaucoma patients and sufferers of certain types of headaches, cramps, and eye pain. Dilation of blood vessels (vasodilation),[35] resulting in:
Increased blood flow and heart rate (possibly even tachycardia) Reddening or drying of eyes Lower blood pressure while standing. Higher blood pressure while sitting (note that this can lead to instances of orthostatic hypotension, also known as head rush).[36] Increased appetite (often referred to as "the munchies"), an effect of stimulation of the endocannabinoid system, which affects body weight, insulin resistance, and dyslipidemia.[37] though recent and anecdotal evidence also points to it as an appetite suppressant. Varying degrees of dry (cotton) mouth[38] Dilation of alveoli (air sacs) in lungs, resulting in deeper respiration and increased coughing. Lethal dose
It is generally considered to be impossible to achieve a lethal overdose by smoking cannabis. According to the Merck Index, 12th edition, the LD50, the lethal dose for 50% of rats tested by inhalation, is 42 mg/kg of body weight. That is equivalent of a 165 lb (75 kg) man ingesting all of the THC in 21 one-gram cigarettes of high-potency (15% THC) cannabis buds at once, assuming no THC was lost through burning or exhalation. For oral consumption, the LD50 for rats is 1270 mg/kg and 730 mg/kg for males and females, respectively, equivalent to the THC in about a pound of 15% THC cannabis. Only with intravenous administration — an unheard-of method of use — may such a level be even theoretically possible.[39]

There has only ever been one recorded verdict (although not ultimately upheld) of fatal overdose due to cannabis. In January 2004, Lee Maisey of Pembrokeshire, Wales was found dead. The coroner's report stated "Death due to probable cannabis toxicity". It had been reported that Maisey smoked about six joints a day. Mr. Maisey's blood contained 130 nanograms per milliliter (ng/ml) of the THC metabolite THC-COOH. However, the validity of the finding did not stand up well under review. As reported on 2004-01-28 in the Neue Züricher Zeitung, the Federal Health Ministry of Switzerland asked Dr. Rudolf Brenneisen, a professor at the department for clinical research at the University of Bern, to review the data of this case. Dr. Brenneisen said that the data of the toxicological analysis and collected by autopsy were "scanty and not conclusive" and that the conclusion "death by cannabis intoxication" was "not legitimate."[40
