Seven days, in case of chronic use of drug
Hi and thanks for the query,
These drugs for sure when taken, especially not for special medical indications, and with specific doses could lead to some personality changes. I do think it is worth testing for these drugs.
It might be worth noting that the ability to detect would depend on the dose taken, and also the route of administration of these drugs. Blood detection could be detected differently if tested in blood urine, blood or hair. Even after a few days of use, the hair could be most suited to still detect.
In her case, if she has been a chronic user, even if she just stopped, it would be possible to detect the drugs if the last day of use dates even up to 7 days ago. A 7 day window exists for her, in case she has been on this drug for quite some time.
