Question
 

Mature – PLEASE keep this mature – if you do not know the answer or can not add something important to the discussion – stay out. I am not saying this as the OP, I am going ahead and posting a warning as a mod. I will remove or delete anything inappropriate or unnecessary.

Okay, sexually transmitted diseases can be passed from one person to the next by the transfer of bodily fluids. The different types of fluids all seem to carry these diseases. I will not name them all.

So, if this is the case, can drug usage be transferred? I know that a pregnant woman can deliver a baby that is addicted to crack and such as that. But, I am referring to two adults. Can someone fail a drug test if the share the same bed with someone who is a chronic drug user?

If not, why?

A NO, this has nothing to do with personal life or a personal experience.

As far as my guess goes, no. Drugs are just chemicals that sooner or later will be flushed out of your body. Plus the amount of drugs transferred will be so miniscule, that there is no real danger of it going in your blood and making you addicted, or upsetting the drug tester machine.

So because it is a chemical that your body immediately starts to break down, it will not be transferred. That makes sense.

What about those drugs though that they say can stay in your system up to 30 days or more?

Then they'll stay in your system for 30 day or more. But once again, very small amounts.

Drugs will be filtered at the kidneys and excreted in urine. However, urine is held at the bladder until a signal to relax is sent (during urination). So I don't see how it can jump to the other person. Assume that it does spit into the air (!!!!), it can't get into the person's body unless it travels through his/her oral cavity. If by chance, it gets into the other person through "that" contact, it should be minimal and the body will act to get rid of it. Sexually transmitted diseases got their names because the acting organisms can invade the reproductive system. I'm not too sure about drugs in general. The rectus (the other opening) is continuous with the gastrointestinal tract which shouldn't have much of the drugs or at all because they're meant to be absorbed into the circulation to exert their effects. Again, we're just looking at possible tranmission pathways in a sexual intercourse. I will say no but I will ask my lecturer when I have the chance because it involves chronic drug use which maintains the drug concentration in the body, so it may do other things I can't think of or actually know of, given my limited knowledge.

I've also always been curious... if someone has AIDS / HIV, and they have unprotected sex with someone that's not infected, its it 100% chance (or very close to 100%) that the other person WILL get the virus??

"Reproduction" lecture series is 1.5 weeks away. I will come back and try to answer this question again, with at least better knowledge than I have now. lol

Meanwhile, any experts in the field please help us. :D

No, transmission of STDs are actually very low. I have still yet to find some good "trustable" sources on that but many google sites says that chances are low. Plus, the show in Forensic Heroes also said the same thing (which was why I had googled it once upon a time for dad, if you remember. No wait, you were out). But once I get time I will go and find some good sites with good scientific information (rather than those "Ask Dr. Blahblah!!").

I am not sure about drugs. I have wanted to look into this when I saw the thread but haven't had the time yet. Though I have usually assumed that no, drugs cannot be transmitted that way.

"Don't be silly, wrap your willy."

lam - when you ask, also ask about the different types of drugs. Do pain killers act differently than….. say cocaine?

Chance of them knowing the answer/coming across literature about this is low because my Physiology department's research interests are muscle/exercise, cardiovascular system and the brain.

it's not "drug" as in "crack". This is about regular medication, as well.

I think that's what Spirit meant.

It is about regular drugs that can and should be prescribed by a doctor, that are taken on a regular daily basis, so they stay in a person’s system – constantly. Not necessarily illegal drugs that can only be bought on the streets.

If STDs and STIs can be transmitted through sex, because they are in the bodily fluids, why can drugs that are also in the bodily fluids not be transmitted?

Germs can be shared by kissing, viruses can be shared by shaking hands. Just wondering why drugs cannot be shared……

And it may be common sense for most people. But, if you know absolutely nothing about medical stuff, drugs, or how things like that works, then you would not know. :lost: I iz stupid when it comes to stuff like that.

Give me a question about financials and taxes and to me it is common sense. However, to some, it may be confusing and make no sense. :smile: I know this stuff very well.

that question asks for a bit more specifics (which pain killer are you talking about). a lot of pain killers work differently, ibuprofen, aspirins, and other painkillers have different "molecular targets" (receptors, enzymes, ion channels or carrier/transport proteins). once a painkiller reaches their target it does what it does (blocks or stimulates the effects that "molecular target" is responsible for) and then slowly gets broken down by the body as others have mentioned.

the answer to your question is yes, cocaine does operate differently to pain killers. cocaine stimulates certain chemicals in the brain - noradrenaline, serotinin and dopamine. however, the site of action for the pain killers i assume you're talking about is not the brain. painkillers usually work by antagonizing receptors in the body and stopping the stimulation of receptors responsible for the feeling of pain and inflammation.

hope this answer helps

ok, I asked a senior tutor today (she completed her Ph.D. ages ago but didn't take up lecturing) and she confirmed all of the opinions thus far: "No, it doesn't happen". She said even in long term, it shouldn't matter much because as far as she knows, that drugs can get into the semen has not been observed or established, unlike in the case of STDs.

So my final answer is: No, the couple should have nothing to worry about.

Cheers,
