Welcome!
Hello and welcome to Wikipedia. We appreciate encyclopedic contributions, but some of your recent contributions, such as your edit to the page Drug test, seem to be advertising or for promotional purposes. Wikipedia does not allow advertising. For more information on this, please see: If you still have questions, there is a new contributors' help page, or you can. You may also find the following pages useful for a general introduction to Wikipedia: I hope you enjoy editing Wikipedia! Please sign your name on talk pages using four tildes ( ~ ); this will automatically produce your name and the date. Feel free to write a note on the bottom of my talk page if you want to get in touch with me. Again, welcome! - Arjayay (talk) 16:26, 17 June 2019 (UTC)

Please do not add inappropriate external links to Wikipedia, as you did to Drug test. Wikipedia is not a collection of links, nor should it be used for advertising or promotion. Inappropriate links include, but are not limited to, links to personal websites, links to websites with which you are affiliated (whether as a link in article text, or a citation in an article), and links that attract visitors to a website or promote a product. See the external links guideline and spam guideline for further explanations. Because Wikipedia uses the nofollow attribute value, its external links are disregarded by most search engines. If you feel the link should be added to the page, please discuss it on the associated talk page rather than re-adding it. Thank you. - Arjayay (talk) 16:31, 17 June 2019 (UTC)
