Step-by-step explanation:
The correct answer is: two to four times stronger than it was twenty years ago.
Today's marijuana has a much higher concentration of THC, the psychoactive compound responsible for the drug's effects, compared to twenty years ago. This increase in potency has been attributed to advancements in cultivation and breeding techniques. Stronger strains of marijuana, such as those high in THC, have become more prevalent in the market.
It is important to note that the potency of marijuana can vary depending on various factors such as strain, growing conditions, and processing methods.
