Yes, marijuana has no affect on the male sperm count, there have been reports that it lowers your sperm count, but however this is not confirmed.
Doug Benson, a famous comedian made a move to document the affects of marijuana to his health, sperm count, etc; entitled "Super High Me" (a spin off name taken from the "Super Size Me") Where he stayed high on marijuana for 30 days (having a full medical exam before and after) and in his tests his sperm count shot up by huge numbers.
However your question entitles "smoking" as the key way of administration, smoking in any form can lower your sperm count, but he would have to smoke an insane amount of pot each day until the tar starts to kill his sperm off.
Hope this answered you question, and BE SAFE!
Always use a condom!!!!
if by smoking for two you mean that you are pregnant. which is something i probably wouldn't do. but there is no real problems that can be found freom smoking marijuana when your pregnant, and everyone i know who has done that have bright children. so i guess it does no harm.
Women don't become sterile from smoking marijuana, it's just unadvised to smoke WHILE already pregnant
Marijuana is not in the genes so it is an environmental factor. If the cannabis consumption has altered the pregnant female's genes then it would be genetic.
Marijuana does not have any effect on a woman's ability to get pregnant.
Same as if he wasn't smoking.
Quit smoking pot!!
Yes, in pregnant mothers the baby`s birth weight can be affected.
You cannot die from smoking marijuana.
Smoking marijuana is awesome
A "bit" of marijuana will do no harm to the fetus, however habitual/daily smoking of marijuana (Or tobacco) will have adverse effects on the unborn baby.
probably, I wouldn't revommend any drugs, alcohol or caffeine when your pregnant Also no smoking
Smoking weed has no bearing on how "strong" a mans sperm is.
