What is necessary for a substance to be classified as in your possession?

For a substance to be classified as being in your possession, it must be under your control. This means that possession is not limited to physically carrying an item on your person or having it located in a specific place, such as your home or a safe. Control implies that you have the ability to access, utilize, or manage the substance, regardless of its location.

In practical terms, even if an item is not directly with you but you can access it at will, it is considered to be in your possession. This understanding is crucial in legal contexts, where possession can influence responsibilities and liabilities related to the substance. Therefore, possession encompasses a broader concept that includes having control over an item rather than just being in the same physical space as it.
