<p>I have a 30+ year old, and there would be a major problem if I found out he brought pot into the house. Or if my nearly 90 something year old mother did. Or a gun, or other illegal drugs, or an uninvited guest without asking first for more than a casual “come in for a moment”, and any number of other things. They are simply the rules of the house. Yes, there are lesser things that I let go, or remark upon with varying intensity, but there are certain things that fall into a category of its own. I don’t even want to get into discussion of cannabis or whether the dirinking age is a sham or carrying a gun is safer than not, or whether a random person I’ve not met is a alright guy.</p>
<p>We went to college reunion this spring with DH’s former roommate and he was the best man at our wedding. Heavy druggie in his day, and spent a lot of time with the same. Vastly successful and well balanced now, and actually he did get through life without his drug use noticeably affecting him adversely. But as he went down the roll call of his former buddies, many of them did not do so well. Far worse than those of any random grouping you could make. </p>
<p>With pot, the dregs stay in your system often for drug testing result to be positive longer than say alcohol, and i would not believe that OP’s son one instant that he does not drive high. He lied straight in his parents’ faces and in a situation that made it clear that it was important, and what he did was quite deliberate here. He bought the stuff, enough for later, stashed in in a container that one doesn’t just pick up anywhere. Transported it to the house. And you are going to believe, that, oh no, he wouldn’t drive under the influence. Pah. I wouldn’t let him drive this summer and he would have to have a clean drug test test before driving my car for a while thereafter. I know three families with guts wrenched up right now because their kids came up positive for some substanced after some driving infraction or accident. All “good” kids. One was active in the drive safe program for the community, which netted him a small artiicle in the local news when he gut busted.</p>
