Many people find it easier to put drug users in a particular box by describing them as being dependent on this or that substance, but this is not always the case. Many recreational drug users often combine two or more different drugs, either to achieve a particular effect or mitigate the side effects of one substance with another. Maybe they just use a different drug depending on how they feel that day.
Combining methamphetamine and marijuana can be a very intense but dangerous experience, but many still try to come down easy from meth by smoking some weed. We won't judge your reasons for doing this, but it does mean you are likely to fail for two different substances in a drug test, so it's only natural to want to know about a good meth and weed detox.
Drug testing for meth and weed
Both meth and weed are part of the SAMHSA-5 group of drugs, so pretty much even the most basic drug test will detect both of them. The weed is of course detected in the THC panel, while the methamphetamines will set off the amphetamines panel.
In terms of detection times, the weed is likely to be the biggest problem in a urine drug test. Methamphetamines, in contrast, should be out of your system in a maximum of six days, so a weeklong detox program will almost certainly do the trick.
If you've only been using weed occasionally, you should be clean in about 7-10 days, which would again fit in reasonably well with your seven-day detox. The main problem with weed, however, is how regular use tends to cause THC to build up in the system, making any detox take much longer. If you've been using weed regularly for a while, you could be talking up to 30 days before you're clean enough to pass a drug test. In extreme cases, it can take even longer.
Is there a quicker meth and weed detox?
It should be becoming clear by now whether you can detox naturally in time for a drug test. If you've been using a fair bit of weed, you may need to consider using a detox drink or some detox pills. These will not clean your body of meth and weed as such, but they will encourage your urinary system to flush itself. This should get enough toxins out of your urine that by the time you take your drug test, you won't test positive for either substance. A typical detox drink takes an hour or two to work and stays effective for a few hours.
If you've been a heavier user, you might want to get a two-stage detox kit. You probably won't find a kit specifically for meth and weed, but you could get a marijuana detox kit and add a meth testing device to it. After using the detox drink and waiting for it to become effective, you'll need to test yourself for both meth and weed before deciding if you need to use the extra supplements.
