I've heard that some people are better at poisoning others, slowly over time. Do a lot of people get away with poisoning? And if so, how do they do that?

Yes, some people do manage to get away with deliberately poisoning others slowly over time. This is often the work of a spouse or partner and the victim may have no idea that they are being poisoned due to slow and gradual delivery.  Someone could poison another slowly by adding small amounts of a toxic substance into their food or drinks over a period of time or even by injecting it into their system slowly over a prolonged period of time.

The poisoner may try to cover their tracks by making the victim appear as if their health problems are simply a consequence of aging or some other natural illness. In some cases, they may be able to convince friends, family and medical professionals that their loved one is simply declining in health due to some underlying condition and not because of any intentional, toxic substances. 

It can be difficult to detect if someone is slowly poisoning another person because the poison does not always lead to an instant or even obvious reaction. Additionally, the substance may be so subtly infused in a person's diet that toxicological analysis may not be able to determine exactly how much and for how long a person has been poisoned. This can make catching a potential poisoner difficult and the motives are often highly personal and hard to prove. 

Whilst people can attempt to poison others slowly, it is important to remember that it is typically an aggravating crime which makes it a lot harder for potential poisoners to escape justice. Additionally, in cases where it is believed that someone is being slowly poisoned, forensic toxicologists can analyze the evidence and medical records in order to determine if a crime has been committed and if so, who is responsible for the poisoning.
