Welcome!
Hello, J02113550, and welcome to Wikipedia! My name is Shalor and I work with the Wiki Education Foundation; I help support students who are editing as part of a class assignment.

I hope you enjoy editing here. If you haven't already done so, please check out the student training library, which introduces you to editing and Wikipedia's core principles. You may also want to check out the Teahouse, a community of Wikipedia editors dedicated to helping new users. Below are some resources to help you get started editing. If you have any questions, please don't hesitate to contact me on my talk page. Shalor (Wiki Ed) (talk) 14:14, 16 January 2019 (UTC)

Recent edit to Cannabis drug testing
Hello, and welcome to Wikipedia. I noticed that you made a change to an article, Cannabis drug testing, but you didn't provide a reliable source. It's been removed for now, but if you'd like to include a citation and re-add it, please do so! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you!
