Unfortunately I knew about quack, too. I couldn’t share with my students that I understood the pain and fear of watching someone you love choose drugs over family and jail time over home time because of that illegal stuff you smoke that’s not at all like cigarettes. I ache for these kids because I once lost a nearly 13 year marriage to a man I chose to love through his addiction to cocaine and then crack. I watched him go through rehab and relapse and then receive a 12 year prison sentence. I had to walk away when he chose the drug over the life we had made together. I know about “quack.”
