Blood tests are generally administered to detect recent use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cannabis (THC) can be detected in the blood in most cases between 1 and 7 days, cocaine between 1 and 3 days, and amphetamine and methamphetamine types approximately between 1 and 4 days. As for synthetic cannabinoids (bonzai), although the detection window varies depending on the contents of the product used, it generally ranges between 1 and 3 days.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, these timeframes are not definitive. In cases of intensive and regular use, detection periods may be prolonged. In judicial investigations, laboratory results are evaluated separately according to the specifics of each incident.
