Answer:
Your grammar is incorrect, but I know what you are trying to convey{complicated for 'SAY'" anyway..
Yes clonazepam{Klonopin} can be insufflated{snorted}
However, some contradiction remains as to the true efficiency of this method of action. Because most drugs in this class benzodiazepines are not very H20{water} soluble, and the nasal passage ways are mainly water absorbent.
From a personal stand point I use alprazolam{Xannax}. I have taken the drug via oral route, sub-lingual, and insufflated. While sub-lingual is the best method insufflation provides a maybe better mental high. I believe it's all psychological, but it does "feel cool" to snort... Kids snort smarty's at school because it's cool.
hope that help's
