I checked at the UPMC site, and I found no such article. However, I did find many articles about a range of topics, including schizophrenia being activated by marijuana use, marijuana causing infertility in men, marijuana harming babies in womb and once born, and an article on drug withdrawal, listing loss of appetite, chills, weight loss, insomnia, sleeping too much, irritability, and nervous tension as some of marijuana's withdrawal symptoms.
Your second and third sites are grossly biased as a source.
