A drug that can make your old memories like new

Edit: The approach here is to create a virus that carries a gene coding for the protein they want to overexpress. The virus inserts the gene into the host cell's dna, which in this case is in the rat's neocortex. They say that expression of this protein is under control of a cytomegalovirus promoter, but I'm not sure if they need to use an additional drug to induce expression.
In any case, the HN title is incorrect.

Edit: Ok I've been snooping around for articles on this and so far I've found these:

Also, methamphetamine has a very high addiction potential. I don't know if this does - I've yet to even glance at the paper - but I would be willing to hedge money on your comparison being between apples & oranges.
Meth makes you vastly more intelligent, that's partly why people get addicted to it. It may impair memory and intelligence in the long term, but this new drug may well do the same, so if you want to do an apples-to-apples comparison then you really have to compare the short-term effects of meth with the short-term effects of this new drug.
Also, I wouldn't say that the addiction potential of meth is that high unless you're abusing it. It's currently a prescription drug that's available to anyone age 6 and over, meaning the government thinks it's less dangerous than marijuana.
