| Moreover, we held in one case that chemical analysis is not an indispensable prerequisite to establish whether a certain substance offered in evidence is a prohibited drug. The ability to recognize these drugs can be acquired without any knowledge of chemistry to such an extent that the testimony of a witness on the point may be entitled to great weight. Such technical knowledge is not required, and the degree of familiarity of a witness with such drugs only affects the weight and not the competency of his testimony.[21] Manikx | |||||
