Er....well if your friend is spending that much time scrutinising photographs and footage of the Pope, perhaps he needs a little more time in rehab.
Opiates
* A person on an opiate such as heroin or morphine will have constricted pupils that will look like pinpoints or small dots.
* Someone on opiates usually itches and you can see the person lightly and frequently scratching himself.
* If the method of ingestion is sniffing, his nostrils may appear raw and red.
* If the method of ingestion is by injection there will be needle marks in arms, behind the knees or ankles.
* Heroin users have been known to inject themselves under the tongue, or directly into open sores. These locations are not as easy to detect.
* They may get very pale and sweaty or extremely thirsty.
* Opiates affect people in different ways: some may get very "hyper"(active or frantic) and run around working or looking busy while others get very lethargic (nodding or doping off).
* The person may go around asking others for money. This will not be small change for cigarettes, but more like $20 or $40 here or there.
* Use or possession of paraphernalia, including syringes, bent spoons, bottle caps, eye droppers, rubber tubing, cotton and needles.
* Slurred speech.
Health
In the early 1990s, Ratzinger suffered a stroke, which slightly impaired his eyesight temporarily. This was known to the Conclave that elected him Pope. In May 2005, the Vatican revealed that he had subsequently suffered another mild stroke; it did not reveal when, other than that it had occurred between 2003 and 2005. France's Philippe Cardinal Barbarin further revealed that since the first stroke, Ratzinger had been suffering from a heart condition as a result of his age, and is currently on medication. Because of these age-related health problems, and in order to have free time to write, he had hoped to retire, and submitted his resignation twice, but had continued at his post in obedience to the wishes of Pope John Paul II. It is also notable that he appears to be in far better health than his predecessor was at the age of 79.[7] In late November 2006 it emerged that Pope Benedict had undergone an operation in preparation for an eventual bypass operation, and that the bronchitis suffered by the Pope has put undue pressure on the Pope's heart
