Wanted to update this and say that DoseTest also has these. They sell the same brand as BunkPolice but sell them for less. They used to be called The HUP. They also have a real cheap reagent kit with 9 reagents. If you buy from them use the code REDDIT and you get 15% off i think. Stay safe every one.
Aside from buying the strips if you live in the US most not ALL states will provide test strips for free or you can go to a Drug Checking Service if where you live allows them or you could look into Reagent Testing which is pretty awesome.
