AITA: Mother does meth, constantly wants to bring my son clothes

AITA for not wanting my mother to give me baby clothes? For context, my mother has been doing meth for about 10 years and goes to goodwill donation bins and takes clothes from them in order to sell them to her friends or on facebook marketplace. When she comes across any article of baby clothing she wants to bring them to me for my child. I truly do appreciate the gesture but I don't like the idea of using stolen clothing or putting these clothes on my son as there is a high possibility of meth being on the clothes. With the fentanyl epidemic taking so many lives and the fact that there could be fentanyl in the meth she smokes makes me not want anything to do with them. Should I tell her how I feel or AITA?
