[|Human|] Hello, I have had the implanon inserted for about 2 years now, I had a lot of spotting and so a couple of months ago I took birth control pills and that made the spotting stop. A couple of days ago I smoked marijuana and suddenly my spotting returned, could the marijuana have caused the spotting?
[|AI|]  Thank you for your question and I will try to help. The most common complaint with these implants (they are progesterone implants) is breakthrough spotting.  Early on after their insertion, this is very common.  Later, such as after 2 years, the lining of the uterus becomes very thin (which is normal) and prone to bleeding.  This can once again be treated with birth control pills.  This has nothing to do with marijuana use.  Finally, make sure that you check a pregnancy test now and in 1-2 weeks. I hope that this helps and good luck!
