alcohol
It is unlikely that cocaine can be absorbed into your skin through touching money that has traces of the substance on it. The amount of cocaine present on a banknote is usually minimal and would not be readily absorbed through intact skin. However, it is always advisable to wash your hands after handling money for hygiene purposes.
Proteins
Water, alcohol, and certain medications can be absorbed through the stomach wall into the bloodstream.
The stomach does not absorb anything. In fact, the stomach secretes a great amount of mucus to prevent the acid in the stomach from damaging the stomach walls. If the mucus were thin enough to allow absorption of chemicals, then you would also have an ulcer from acid damage.
The percentage of alcohol that is absorbed through the small intestines is 80%. The remaining 20% of alcohol consumed is absorbed through the stomach.
Water
The digestive system changes food into a soluble substance. This process involves mechanical digestion (chewing and churning) in the mouth and stomach, as well as chemical digestion through enzymes in the stomach and small intestine that break down food into nutrients that can be absorbed by the body.
Light can be absorbed by the substance, reflected off the substance, or transmitted through the substance.

It is transmitted.
Ibuprofen is mostly absorbed in the duodenum (small intestine). It cannot be absorbed through the lining of the stomach due to its low solubility in water and the low pH of stomach acid (since ibuprofen dissolves in water better at higher pH's).
liquids that are isotonic (about a 1% solution) [except for alcohol which can be absorbed directly through the stomach.]
