active ingredients contained in marijuana

Could "active ingredients contained in marijuana" be written as "active ingredients of marijuana" without affecting its meaning?

With "of" there, there appears to be more senses that would be misleading in some ways that I can't tell.

“This approval serves as a reminder that advancing sound development programs that properly evaluate active ingredients contained in marijuana can lead to important medical therapies,” FDA Commissioner Scott Gottlieb said in a statement. “And, the FDA is committed to this kind of careful scientific research and drug development.”

    Yes, I think so.

    But I’d prefer to add “the” to the sentence - in both the long or shorter version.

    I am not so sure. We do not usually talk of a plant as being made up of ingredients. Rather, the plant contains substances that are used as ingredients in other (man-made) products. The phrase "ingredient(s) contained in" is common.
