Other than the fact that they both derive from plants and both are drugs, there is no link. No, using one does not lead to use of the other. Heroin comes from opium, as do morphine and codeine. Marijuana, most often used in it's original form is a completely unrelated plant with very different effects.
Heroin, also known as diamorphine is a semi-synthetic opioid drug witch is synthesized from morphine. Morphine is a alkaloid extracted from the opium poppy plant, morphine acts directly on the central nervous system to relieve pain.
Cannabis is an illegal drug bought off dealers, this brings it's users in contact with hard drugs such as heroin. Nearly all heroin users used to be cannabis smokers.
Both Heroin and Morphine are narcotics of a class known as "Opioides."
heroin is a bad drug and so is morphine
Both. It originates as opium from opium poppies, which is then refined using chemicals into morphine. Morphine can then be further refined and condenced with a final result of much more effective heroin.
Morphine
morphine
Yes, Heroin - 5 times to death Morphine - 10 times to death
You test positive for morphine after you use heroin
The two aren't normally combined if you are performing a chemical reaction of morphine to get heroin then you would either have morphine or heroin if your actually taking morphine and mixing it with heroin then stop doing that if you don't want them mixed together.
Heroin is metabolized into morphine inside the body. Heroin is the 3,6-diacetyl ester of morphine, and these ester groups are cleaved in vivo to produce morphine.
opiates (heroin, opium, codeine, morphine)
Methodone heroin
Heroin breaks down into codeine and morphine. Codeine breaks down into morphine. The opiate drug tests look for codeine, morphine, and 6-acetyl-morphine. The presence of 6-acetyl-morphine is relatively conclusive of recent heroin use, but is only detectable for a few hours after use. The presence of codeine can be the result of either heroin or codeine use. The presence of morphine can be the result of the use of heroin, codeine, or morphine. Relative levels of codeine and morphine can help determine their origin.
