What should i do? military question?

long story short I was with wrong people who were smoking MJ, I got cited for secondhand smoke. Public intox. However I was not arrested, the judge dismissed the charges and there was no adverse disposition at all. I joined the army a while before this. My recruiter told me not to mention anything when I go down to MEPs this second time and dont say anything during reception but tell the truth on the SF-86. I do not want to get kicked out for fraudulent enlistment. hes kinda pushing me to lie, small threats even. What should I do? Should I talk to another recruiter? or should i mention it at reception? will it require a waiver? and if i do mention it at reception will i get kicked out? i really need help guys. im supposed to leave at the end of this month
