Jo, old prude Lou is telling you to not cave into Andy's offer of drug cakes/smokes/pills or any other form of intoxication/getting high.

Andy can get stupid (slang for druged-up mind) any times he wants to. He and BIL can plot against you, either now or use the fact you used with him some time later. If you think taking depression meds can be used against you in court, you taking the drug cakes in the US carries more weight than perscription drugs taken per Dr's orders.

From reading your story, I think I would have taken D4 and gone home earlier. I might have even asked OW1 or her SO/BF to drive me home. Sometimes it sounds like the more you agree to his requests, the more he manipulates you.

About you
Your posts make it sound like are having some mental stability problems. You know fighting with Andy are mostly the cause don't you?

I am glad to hear you and D4 are not gong to spend the New Year with Andy. You don't need the grief Andy makes for you.

BIL is bi? O my gosh. That is not what you need either. I suppose he treats you betrter than Andy does right now but I don't think either one is going to give you anything but trouble in the long run.

It is not proper of me to suggest what you do, but when someone hinted you, D4, and D3 run away from Andy so he can't find you all for a couple of years, that made me say "yes."

I am not suggesting you do it with D3 and D4 but quit going to Andy's house for a long while, for your own mental health.
