What are the pros and cons of spray test?

Pros: Spray (Sweat) drug test kits are non-invasive and donor friendly. It is very easy to collect the specimen and no bathroom is needed for taking the specimen. The detection window is long and usually can detect drug use up to a couple of weeks. These drug tests are relatively tamper proof since they are hard to manipulate. There is no need for a lab and you can get results in minutes. Cons: The main disadvantage of spray or sweat based drug testing is the fact that they are open to contamination. Also, large variations of sweat production rates of possible donors make some results inconclusive. There is not much variety in these drug tests since they are not as popular as urine or saliva drug testing kits. Their prices tend to be a little higher per test conducted. One main disadvantage of this testing method is the limited number of drugs that can be detected.
