More strength years ago!
I'm not sure why you think that's the case? Research shows it isn't. Pasting below what I just shared with another poster.
Strength wise, it's a different ball game now even compared to 10 years ago.

The research referred to showed that in 2016, 94% of police seizures were high-potency marijuana, compared to 85% in 2008 and 51% in 2005. The drug contains more of the psychoactive ingredient THC than some other types of cannabis, such as hash.
The researchers say their latest work, published in the journal Drug Testing and Analysis, is the first comprehensive survey of cannabis strength published in the UK for nearly a decade.
They analysed police seizures of cannabis from London, Kent, Derbyshire, Merseyside and Sussex in 2005, 2008 and again in 2016.
Skunk was the dominant street drug over this time period, while the availability of weaker cannabis resin went down - from 43% in 2005 and 14% in 2008, to 6% in 2016.

For additional context, in the 70s the maximum THC levels available were still under 5%. In the last couple of years the average level in resin has been 4-6% and the average in sinsinella (which forms more than 90% of the market) has been 14%.
