No. The part of marijuana that gets you high is called
`Delta-9-tetrahydrocannabinol.' Most people just call this
THC, but this is confusing: your body will change
Delta-9-THC into more inert molecules known as
`metabolites,' which don't get you high. Unfortunately,
these chemicals also have the word `tetrahydrocannabinol' in
them and they are also called THC -- so many people think
that the metabolites get you high. Anti-drug pamphlets say
that THC gets stored in your fat cells and then leaks out
later like one of those `time release capsules' advertised
on television. They say it can keep you high all day or
even longer. This is not true, marijuana only keeps you
high for a few hours, and it is not right to think that a
person who fails a drug test is always high on drugs,
either.
Two of these metabolites are called
`11-hydroxy-tetrahydrocannabinol' and
`11-nor-9-carboxy-delta-9-tetrahydrocannabinol' but we will
call them 11-OH-THC and 11-nor instead. These are the
chemicals which stay in your fatty cells. There is almost
no Delta-9-THC left over a few hours after smoking
marijuana, and scientific studies which measure the effects
of marijuana agree with this fact.
