Drug testing kits for Cannabis have been available to purchase online now for about 14 years and have proven to be reliable, accurate & easy to use.
The most popular drug testing kits that detect cannabis use are urine drug testing kits. They can be purchased as either an individual drug test (usually either a drug testing strip or cassette ) detecting only Cannabis or as part of a multi-panel drug test kits that detects multiple drugs.
Cannabis oral drug test kits are also available to test a saliva sample, and these usually form part of a 6 in 1 or 7 in 1 saliva drug test panel. These are popular for workplace drug screening as you can be sure that the sample has not been tampered with.
Cost wise saliva testing tends to be a little more expensive than urine drug testing and the detection periods are usually shorter.
For home drug testing a urine test for cannabis is probably the best choice as the detection period can be up to 28 days if Cannabis use has been heavy & prolonged.
