Karen....it will be very hard not to get involved but i think you should stay clear....but try to help the kids understand the dangers and help them stay clear of it too.....
this is a lesson for them too to see what a mess pot smoking can be and the trouble it can cause....this role is one of guidance and hope the kids heed the knowledge...but still keep an eye on things....so much for kids and parents today to deal with...hugs Sassy
