Since most of the people are not sure of how weed works, this is a primary reason why people believe that inhaling secondhand smoke from a weed may cause them to go dizzy, or feel the buzz.

Poppy Seed Dilemma

Many non-smokers often wonder why their test results showed a fake positive when they never used the drug in the first place. The answer is very simple and a part of most of our daily diet. 

Similar to other test results, there can be multiple factors that can influence the drug test results to deteriorate and show a false positive. It is recommended that if you are unsure of why the results of the test are unfavorable, you should re-think what you did or eat before the time of the test. It allows you to trace back to the actual reason which may have caused the test results to be affected. Once you are sure of what the reason would have been, try to avoid that and retake the test to ensure that your assumption was correct.

Poppy seeds are famous for being one of the reasons to show a false positive in a test result. According to studies, it was found out that eating raw poppy seeds before a drug test would result in a false positive. However, there is no harm in eating prepared poppy seeds. 

If you’re a frequent consumer of poppy seeds, it is best if you avoid them a day or two before your drug test. Studies have shown that consuming poppy seeds the same day as the test results would like to cause the test to show a positive. However, if you take the test a couple of days after you’ve last consumed the seeds, it would not have any effect on the test results what so ever. It is better to avoid these secondhand weeds.

Secondhand smokers test results may show increased THC levels, however, if they have only been exposed to the smoke, their results would still be less than the required threshold. If the secondhand smoker is also a habitual poppy seed consumer, their drug test results might indicate a false positive, given that they have taken the test the same day as they have consumed the seed on. 

If you’re not a smoker it is best to keep away from an environment where you can be exposed to secondhand smoke as it can show up on drug tests.
