Is Ranitidine Or Levomethamphetamine Similar To Amphetamine?
tricky on a number of issues
Detailed Answer:
Hello again!
First, I don't think abuse and dishonesty are a good idea.
The cross reactivity is on the basis of what test and how close the chemicals are to each other. Obviously, the chemical in decongestants is quite close to amphetamine, but it should be distinguishable in a Mass Spec testing (but it sure will cross react in an antibody/dipstick testing).
They can do hair testing to really get a lot of data and that test is only done by Mass=Spec.
Other compounds are thought to cross react to amphetamine. I do not recall ranitidine as being one of them BUT, it sure isn't as close as decongestants.
There are always other methods that will learn the truth. There is also testing for the particular breakdown products and these will also be somewhat different.
In short, honesty is the best policy.
